Kelvin de Ruiter: the profile of a Dutch strongman giant

Kelvin de Ruiter is one of the most significant Dutch strongmen of his generation and one of those athletes whose career cannot be reduced to a single title or one spectacular photograph. Born on 31 March 1988 in the Netherlands, he has built a competitive identity over more than a decade and a half that is unusually clear: an exceptionally tall Open-class athlete at 2.03 metres, with bodyweight varying by season and source, best known for vehicle pulling, posterior-chain strength and the ability to stay competitive through dense international schedules. Strongman Archives lists him as active from 2011 through 2026, with 46 international contests and eight international wins, 14 national appearances and four Strongest Man of the Netherlands titles, together with one World's Strongest Man appearance. Beyond the raw numbers, de Ruiter's career is the story of an athlete who developed gradually through many seasons of accumulation before reaching his broadest international peak in 2021.

Two nicknames appear repeatedly in his public profile and capture different sides of his sporting identity. Giants Live calls him “Big Boss”, a name associated both with his physical presence and with his own training base, Big Boss Gym in Harkema. His personal website also uses “The Flying Dutchman”, a label that frames him as a Dutch representative on the international circuit. Inside strongman, however, his reputation is tied above all to truck pulling. He is not merely an athlete who happens to be good at pulls. He became one of the most accomplished vehicle-pull specialists of the modern era, winning the SCL World Truck Pull Championships in 2017, 2019, 2021 and 2023. His competition record includes event wins with trucks and other vehicles across a wide range of masses and configurations, with harness only, with rope, or with a combined harness-and-rope setup.

The strongest title run of his career came between 2019 and 2023. In 2019 he became Strongest Man of the Netherlands for the first time after years of climbing gradually from mid-table national finishes to the podium. In 2021 he retained national supremacy, won a third SCL World Truck Pull Championship and, most importantly, won the SCL World Finals in Alanya, a result that also delivered the overall Strongman Champions League title. A third Dutch championship followed in 2022 and a fourth in 2023, along with another world truck-pull title in South Africa. That sequence places him among the most accomplished Dutch strongmen of the modern period and makes him one of the defining SCL athletes of the early 2020s.

Origins, youth and the discovery of strength

Dutch interviews describe a beginning very different from the biographies of lifters directed into weightlifting or powerlifting from childhood. De Ruiter has said that he had always been fascinated by heavy things, but his unusual physical strength became more obvious during his late teens and early adult life. He had a background in kickboxing before committing to strongman, and manual work played a direct role in revealing his ability. While working part time at a vehicle breaker’s yard, he noticed that he could lift and move objects that were much more difficult for other workers to handle. Giants Live summarises this phase by noting that he discovered his strength while lifting cars and heavy objects in the yard. The story appears consistently across athlete profiles and interviews: strength first appeared as something useful in everyday labour, and only later became the basis of a competitive career.

In an RTV NOF interview after the 2021 season, de Ruiter described his 19-year-old self as a “dunne spijker”, literally a thin nail, meaning extremely slim compared with the massive physique he later built. That detail matters when evaluating his development. At 2.03 metres, an athlete needs years to fill such a long frame with useful muscle mass and to turn long levers into a competitive advantage. De Ruiter did not simply arrive as a fully formed heavyweight giant. He accumulated body mass, technique and tolerance for training volume over time. His father was involved in his early training, and he later came under the guidance of Wout Zijlstra, the Dutch strongman who placed third at the 1998 World's Strongest Man final. That connection gave de Ruiter access to technical strongman knowledge in a country that already possessed a substantial tradition in the sport.

The link between strength and manual work remained part of his life long after he became an international athlete. De Ruiter is a carpenter by trade and has worked in construction, including as a self-employed tradesman. Even after he had collected major international titles, local reporting in 2021 still described him dividing his time among work, his own gym and SCL preparation. Giants Live wrote in 2022 that his working day could begin at 6 a.m. and include roughly ten hours of labour before training. That context explains an important part of his career. He was not built from the beginning inside a fully professional system with the whole day available for recovery, food and sport. Much of his rise happened alongside physically demanding employment, making his long-term consistency particularly notable.

The early Strongest Man of the Netherlands years: 2011–2016

Competition archives place de Ruiter at Strongest Man of the Netherlands as early as 2011. He finished eighth of twelve in Surhuisterveen. For an athlete who would later become a four-time national champion, the overall debut result was not spectacular, yet the individual events already showed elements of the profile that would eventually define him. He placed third in the truck pull and produced competitive results in Atlas Stones and Carry & Drag. In 2012 he slipped to eleventh, then climbed to fourth in 2013. The first national podium arrived in 2014 with third place. The sequence illustrates real but uneven development. It was not a straight line toward dominance, but a gradual process of building strength, event technique and the ability to manage a multi-event contest.

Also in 2014, de Ruiter produced an important formative international result, finishing eleventh of 31 at the European Amateur Strongman Championships in Vilnius. The overall placing was not yet elite, but several event results showed his potential. Strongman Archives records third in the farmer's walk, fifth in Atlas Stones, and sixth in both shield carry and super yoke. Those numbers suggest that even before international recognition he had surprising mobility and speed for his size. What he lacked was consistency across an entire event set, one of the classic problems in strongman development. A single poor event can erase the advantage created by two or three excellent ones. His seventh place nationally in 2015 and fifth in 2016 fit that transitional pattern.

This early phase also challenges the idea that de Ruiter was a complete specialist from the beginning. Very tall athletes can hold natural advantages in pulling, carries and some medleys, but may struggle with overhead positioning, rapid transitions or events requiring compact body angles. De Ruiter had to build a broad enough profile to win complete contests rather than isolated events. By 2016 he was an established national finalist but not yet a champion. That continuity became the foundation for the next stage: regular international SCL competition and the transformation of truck pull from a strong event into a true competitive weapon.

2017–2019: from specialist to national champion

The 2017 season marked the international turning point. Domestically, de Ruiter returned to the national podium with third place. More importantly, he won the SCL World Truck Pull Championships in Amman, Jordan. The contest used multiple pulling formats, and de Ruiter displayed the combination of body mass, efficient lean angle, hip strength and the ability to maintain short powerful steps under tension that would become his trademark. Strongman Archives records event wins for him in truck pull and arm-over-arm during that championship. The title shifted his status from solid national competitor to athlete with a world-class speciality. In strongman, winning a single-event world championship does not guarantee overall success, but it can create a signature. Truck pull became exactly that for de Ruiter.

In 2018 he competed more regularly in Strongman Champions League. He was seventh at SCL Abu Dhabi, fifth at SCL Holland and tenth at SCL Romania. At national level he improved to second, behind Alex Moonen. The event data already show a high level of consistency in heavy dynamic work. He won the truck pull at SCL Holland and placed second in the same event in Abu Dhabi. His public identity became increasingly linked to the speciality, and Dutch media were already presenting him as a world champion truck puller. At the same time, improvement in stones, yoke and loading allowed him to collect enough points for better overall finishes rather than relying on one event.

The 2019 season brought full competitive maturity. On 7 July in Weert, de Ruiter won Strongest Man of the Netherlands for the first time. It was his ninth consecutive recorded appearance at the national final, after a progression through eighth, eleventh, fourth, third, seventh, fifth, third and second. The victory also carried a heavy personal meaning. Regional reporting stated that his father, Tjitze, and a coach who had stood beside him from the beginning had died during the period leading up to the championship. De Ruiter went through a period in which his motivation to train collapsed. A thigh injury shortly before the contest further complicated preparation. He nevertheless competed and won the national title that had become a shared family objective. It is one of the clearest moments in which his sporting career and personal life intersect.

Internationally, 2019 was one of his busiest seasons. He placed second at SCL Holland, third at SCL Russia and SCL Serbia, and fourth at World Record Breakers before winning another SCL World Truck Pull Championship in Kyiv. In October he also won SCL Curaçao overall. The Kyiv truck-pull championship required athletes to move vehicles across different pulling events, including very heavy trucks, and de Ruiter emerged as overall champion. By the end of 2019 he possessed his first Dutch national title, two world truck-pull championships and an SCL stage victory. His international standing had changed dramatically in only two years.

2020: the Guinness record and a disrupted season

The 2020 season was unusual across international strongman because of the pandemic and the sharp reduction in travel and contests. De Ruiter still made several SCL appearances, finishing ninth in Norway, sixth in Finland and second at the SCL World Record Breakers in Germany. The final contest produced one of the clearest statistical landmarks of his career. On 26 September 2020 in Germany, he performed a 670 kg Viking Deadlift, a result recognised by Guinness World Records as the heaviest Viking deadlift in competition. The mark is important because it shows that his strength extended far beyond horizontal pulling. A 670 kg Viking deadlift is a specialised lift with its own leverages and range of motion, but it still demands extraordinary hip and back extension strength.

Guinness explicitly records Kelvin de Ruiter, the 670 kg load, the German location and the date of 26 September 2020. That independent certification is particularly valuable in strongman, where records can be difficult to compare when machines, pulling heights, angles and equipment differ. In this case, the performance has clear external recognition. Strongman Archives also shows that despite the shortened season, de Ruiter remained close to the top of the SCL field by finishing World Record Breakers second overall. The disruptions of 2020 interrupted momentum but did not end the upward cycle that had begun in 2017.

2021: the defining season and the Strongman Champions League title

If one season must be chosen as the competitive peak of Kelvin de Ruiter's career, 2021 has the strongest case. He opened the main international run with second at SCL Norway, then took third in Portugal and second at World Record Breakers. On 14 August in Kampen he won Strongest Man of the Netherlands for the second time. On 19 September in Kyiv he captured a third SCL World Truck Pull Championship. Those performances strengthened his position in the annual SCL standings and brought him to the Alanya final as a genuine title contender. Unlike 2019, when his truck-pull speciality often stood out more strongly than his overall placings, by 2021 he had become complete enough to win a seven-event international final.

The 2021 SCL World Finals in Alanya, Turkey, featured twelve athletes and seven scoring elements. De Ruiter finished with 68 points, 1.5 ahead of Aivars Šmaukstelis. He won the block press, natural stones and the medley, while the preliminary score also contributed to his advantage. The critical point is that the victory was not dependent on truck pull. In fact, one of the most revealing aspects of the final was his versatility: efficient block pressing, fast natural stones and a winning medley. That is why the 2021 SCL title is more than an extension of his reputation as a vehicle puller. It is evidence of the season in which he turned specialised strengths into a sufficiently complete package to win a league championship.

The 2021 success also had national significance. De Ruiter became the first Dutch athlete widely credited with winning the overall Strongman Champions League title. Regional media in Friesland treated the result as a move from respected international athlete to a name at the front of the sport. At the same time he spoke openly about the less glamorous side of elite strongman: the cost, the need to keep working and the amount of food required. During contest preparation he described eating around 8,000 calories per day, built from large amounts of pasta, meat, eggs, rice and protein shakes. He did not present the diet as spectacle so much as logistics. Maintaining the body mass required for Open strongman was expensive and time-consuming, while prize money did not automatically make the sport financially self-sustaining.

2022: Giants Live, Europe's Strongest Man and World's Strongest Man

The SCL championship opened the door to Giants Live in 2022. On 2 April, de Ruiter competed at Europe's Strongest Man in Leeds and finished ninth of twelve. For a debut on that stage the result was solid, and his best event came in Carry & Drag, where he placed second. In Atlas Stones he completed five stones from 100 to 180 kg in 30.60 seconds. He also entered the World Log Lift Championships held in the same event but did not register a successful maximal log. The contrast fits his broader profile: highly effective in locomotion, pulling and loading, less dominant in maximal overhead pressing when compared with the world's best specialists.

In May 2022 he received the invitation to World's Strongest Man in Sacramento, California. De Ruiter competed in Group 5 and finished fourth of six, missing the final. Strongman Archives records one WSM appearance and no final, with fourth in the group as his best finish. Even without reaching the final, the appearance is a major biographical milestone. World's Strongest Man remains the best-known competition in the sport for a global general audience, and qualifying placed de Ruiter among the relatively small group of Dutch strongmen who have appeared there. For an athlete who had finished eleventh at the Dutch championship a decade earlier, Sacramento represented the realisation of a goal he had discussed publicly in 2021.

The rest of 2022 showed that WSM was not an isolated peak. De Ruiter won SCL Holland in Doetinchem, taking event victories in Atlas Stones, Conan's Wheel and Super Yoke. On 9 July he became Strongest Man of the Netherlands for the third time. In SCL he placed third at World Record Breakers and in Serbia, sixth in Poland and fourth in Gibraltar, then won SCL Romania in Sibiu, including first in frame carry and truck pull. He closed the SCL World Finals in seventh. Overall, 2022 did not match the brilliance of the 2021 league title, but it was arguably his broadest season in terms of international exposure: Giants Live, WSM, another national championship and two SCL stage wins.

2023–2026: a fourth Dutch title, a fourth truck-pull world title and continued longevity

In 2023 de Ruiter remained among the leading Dutch strongmen and returned to SCL podiums. He was fifth in Finland, third in Serbia and second at SCL Holland. On 8 July in Winschoten, he won Strongest Man of the Netherlands for a fourth time. The event breakdown explains the victory clearly: first in Atlas Stones, first in Super Yoke and first in Truck Pull, second in farmer's walk and second in the log lift with 160 kg. It was not a championship obtained through one speciality but a competition in which he scored heavily across many movement patterns. With titles in 2019, 2021, 2022 and 2023, he secured his place among the multiple champions of recent Dutch strongman history.

On 21 October 2023 in Kroondal, South Africa, another major landmark followed: a fourth SCL World Truck Pull Championship. De Ruiter won the contest with 32 points ahead of Adam Roszkowski and Kelin Mills. In the first truck pull, 12,000 kg over 25 metres with harness only, he stopped the clock at 21.25 seconds and won. In the final truck-pull discipline, 20,000 kg over 25 metres with harness and rope, he won again in 20.25 seconds. Fifth place in the arm-over-arm event did not erase the advantage. The result also matters for historical accuracy because several older athlete profiles still call him a three-time world truck-pull champion. Updated 2023 results support the correct current description: four titles, won in 2017, 2019, 2021 and 2023.

The 2024 and 2025 seasons showed a changing balance in Dutch strongman as Kevin Hazeleger and a newer generation rose, but de Ruiter remained highly relevant. In 2024 he finished second at SCL Martinique and second at Strongest Man of the Netherlands, where he won the car deadlift and truck pull. He was sixth at SCL Dubai and continued to win or podium in pulling events. In 2025 he placed third at the national championship in Weert. There he won the truck pull and, significantly, the max deadlift with 400 kg, which Strongman Archives now lists as his competition max deadlift PR. At SCL Holland in 2025, despite a weaker overall result, he again won the truck pull. The speciality that had defined his international career remained intact.

In 2026 Strongman Archives records an appearance at the Rebellion Strength Festival in Timișoara, Romania, where de Ruiter finished eleventh. The result is far from the title-winning seasons, but it confirms that he was still competing at age 38. In a sport where cumulative wear is substantial and event demands change continually, that longevity has value of its own. From the 2011 Dutch final to the 2026 Romanian contest lie fifteen years of archived results. For a heavyweight over two metres tall, with thousands of heavy repetitions, years of manual work and dozens of international trips behind him, such continuity is a central part of his athletic legacy.

The anatomy of a truck-pull specialist

Truck pull is one of the most difficult strongman events to standardise. Vehicle mass is only one variable. Rolling resistance, gradient, surface, tyre pressure, wind, course length, use of a rope and harness configuration all matter. Raw comparisons by tonnes can therefore be misleading. What makes de Ruiter's record remarkable is not one isolated number but repeated success in different conditions. He has won pulling events at world championships, SCL stages, national championships and season finals. In 2022, for example, Strongman Archives records truck-pull victories for him at SCL Serbia, SCL Poland, SCL Romania, SCL Gibraltar and the SCL World Finals. In 2023 he won truck pulls at SCL Holland and the Dutch championship before winning both truck-pull disciplines at the world event championship.

Biomechanically, a 2.03-metre athlete weighing around 168 kg carries several natural advantages. High body mass contributes to traction and allows more force to be transferred into horizontal acceleration. Long limbs can create an effective body angle and efficient stride if ankle mobility and pelvic control are sufficient. Yet the same height can become a disadvantage if the athlete cannot stay low, keep constant tension in the harness and avoid slipping. De Ruiter refined that movement pattern over years, and his results suggest a rare ability to break the vehicle from rest, the hardest phase, then maintain rhythm once rolling resistance falls. In rope-assisted pulls, coordinating the upper-body pull with leg drive adds another technical layer in which accumulated experience matters enormously.

His speciality did not prevent him from building very high deadlift strength. The Guinness-recognised 670 kg Viking deadlift and the 400 kg max deadlift at the 2025 national championship point to a posterior chain capable of both maximal pulling and sustained grinding effort. In car deadlift, de Ruiter performed three repetitions with a 400 kg listed load in 2019 and eleven repetitions in a car-deadlift setup at SCL Serbia 2024, winning the event. These performances cannot be compared directly because strongman machines differ, but they help explain mechanically why truck pull became such a weapon. Glutes, hamstrings, spinal erectors, grip and tolerance for long high-tension effort were developed at an exceptional level.

Strengths, vulnerabilities and competitive style

Across a long career, de Ruiter's strengths form an interesting hierarchy. Vehicle pulling is clearly first, followed by special deadlifts, yoke, carries and certain medleys. Yet his 2023 national championship shows why he cannot simply be described as “the truck-pull guy”. He won Super Yoke and Atlas Stones there as well. At SCL Holland 2022 he was first in Stones, Conan's Wheel and Yoke. At the 2021 World Finals he won block press, natural stones and the medley. That variety explains his general titles. A pure specialist can win one event. To win an entire league or national championship, the baseline must remain high almost everywhere.

Maximal overhead pressing, by contrast, has not consistently been the area where de Ruiter dominated elite opposition. Strongman Archives currently lists a competition log best of 160 kg, while Giants Live published a 175 kg training lift. Both are enormous in absolute terms, but they are modest relative to the specialist standards of world-class log lifting. At Europe's Strongest Man 2022 he did not record a successful lift in the World Log Lift Championship segment, and overhead events cost him points in several SCL contests. Very fast events with many implement changes could also magnify the difficulties of moving a 2.03-metre heavyweight body. He compensated through efficiency in heavy moving events, experience and an ability to recover points whenever the event suited his leverages.

Another important trait is competition durability. Strongman Champions League often demands repeated travel through different countries, surfaces, equipment standards and weather conditions. In 2019, 2022 and 2023 de Ruiter completed busy seasons with multiple podiums and event wins. The ability to return after a poor finish, manage accumulated soreness and continue competing was almost as important as absolute strength. This is one reason the 2021 SCL championship carries weight. A league rewards not only one perfect day but availability, consistency and the accumulation of strong performances across a season.

Work, Big Boss Gym and life outside competition

De Ruiter's life outside the arena has long been tied to manual work and his local community in Friesland. He is a carpenter and has worked in construction, including self-employed work. Dutch reporting presents that occupation repeatedly rather than as a minor biographical footnote. For much of his career strongman did not generate enough income for him to stop working, and he explained openly that employment was necessary to finance food, travel and training. In 2021 he said there was not a great deal of money in the sport for him and that food alone represented a major cost. That reality places him within a traditional European strongman model in which even international competitors often maintain trades or businesses alongside elite competition.

Big Boss Gym in Harkema became an important centre of his sporting life. A 2019 VICE Netherlands report described it as a space specifically adapted to strongman, with very heavy Atlas stones, tyres and implements that ordinary commercial gyms may not accept. De Ruiter joked that he had once bent a bar under excessive load and that some gyms were not enthusiastic about the noise and nature of his training. Owning a gym allowed him to keep contest implements available, reproduce events and train with other local strongmen. In a sport built around specialised objects, permanent access to equipment is a major advantage. Truck pull, yoke and Atlas stones cannot be prepared optimally using only conventional fitness machines.

His size inevitably became part of everyday life and media coverage. Interviews describe practical issues around clothing, eating and recovery, but also unusual requests to use his strength outside competition. Panorama reported in 2022 that de Ruiter had been asked whether he could lift a palm tree onto a roof terrace and that he had managed to set a locomotive of roughly 100 tonnes in motion during a strength demonstration. Such anecdotes should be treated as journalistic reports rather than standardised records, yet they show how the identity of “strongest man” travels beyond the contest field into public life.

Nutrition, recovery and the physical cost of strongman

De Ruiter has spoken in several interviews about the amount of food required to maintain his body mass and training. During peak competitive periods he has cited roughly 8,000 calories per day, while in a February 2022 interview he said he was eating around 6,100 at the time and effectively considered himself to be “dieting” relative to the summer season. Publicly described foods include pasta, rice, meat, eggs and protein shakes. These numbers should not be treated as nutritional advice for ordinary athletes because his requirements are tied to a body well over 160 kg and an extreme training load. Their biographical value is different: they reveal the daily financial, digestive and logistical cost of maintaining an Open strongman physique.

Recovery is another recurring theme in reporting about him. VICE described regular massage work inside Big Boss Gym, and de Ruiter joked about how difficult it was to find therapists physically capable of working effectively on such a large body. Beneath the anecdote lies a real biomechanical issue. High volumes of deadlift, yoke, truck pull and stones create severe stress on the back, hips, knees, elbows and connective tissue. Fifteen years of archived competition suggests that he managed those demands well enough to sustain a long career. De Ruiter has also discussed medical monitoring and blood pressure in published interviews. Such material is best treated as his own statements at the time, not as an external medical assessment.

Family, loss and the personal dimension

Public information about Kelvin de Ruiter's romantic life is limited, and it would be inappropriate to fill the gap with speculation. Available biographical sources speak more clearly about his parents and the environment in which he grew up. Regional reporting notes that the family lived for a period in Wieringen before moving to Surhuisterveen. His father, Tjitze, and mother, Monique, were at one point associated with running a local café, according to a regional article. More directly relevant to his athletic story is the role of his father in his early years and the impact of his death before the 2019 national championship. De Ruiter was described as temporarily losing the desire to train before people around him helped him reconnect with the shared ambition of becoming the strongest man in the Netherlands.

Because strength athletes are often portrayed only through numbers and records, the 2019 episode matters. It shows an athlete whose motivation was not mechanical or permanently stable, but shaped by relationships, grief and personal meaning. Winning the national title after that period became more than a statistical result. Without turning the story into mythology, it is fair to note that his first championship carried an explicit family significance. In later years de Ruiter maintained a comparatively direct public presence built around training, work, contests, gym life and regional appearances rather than a heavily manufactured celebrity persona.

Records and performance landmarks

When discussing de Ruiter's records it is important to separate officially recognised records, competition results and training lifts. The clearest external certification is the 670 kg Viking Deadlift from 2020, recognised by Guinness World Records. Strongman Archives currently lists a 400 kg max deadlift from the 2025 Strongest Man of the Netherlands and a 160 kg competition max log from the 2023 national championship. Giants Live published a 175 kg training log and a 370 kg deadlift in an athlete profile written before the 400 kg result. For an up-to-date profile, the 400 kg figure therefore has priority as the more recent documented competition max.

The vehicle-pull numbers are spectacular but always require context. At the 2023 World Truck Pull Championships he pulled 12,000 kg over 25 metres in 21.25 seconds with harness and no rope, then 20,000 kg over 25 metres in 20.25 seconds in a harness-and-rope setup, on a course described in some sources as slightly downhill. At the 2023 Strongest Man of the Netherlands he won a 16,000 kg truck pull over 20 metres in 26.70 seconds. In 2019 he performed three repetitions on a 400 kg listed car deadlift at World Record Breakers. These numbers help demonstrate the scale of his strength, but they should not be compared mechanically with records produced on different machines or surfaces.

Kelvin de Ruiter's place in Dutch strongman

The Netherlands has an important strongman history, with names such as 1992 World's Strongest Man champion Ted van der Parre, Berend Veneberg, Wout Zijlstra and many national champions who kept the discipline visible. De Ruiter belongs to a different competitive generation, shaped by an era in which Strongman Champions League offered a denser international schedule and the possibility of competing repeatedly across Europe and beyond. His four national titles place him among the prominent multiple champions of recent history, while the 2021 SCL crown gives him an international distinction achieved by very few Dutch athletes. His 2022 WSM appearance completes that line of progression even though he did not reach the final.

His legacy is more specific than a trophy count. In the history of modern vehicle pulling, de Ruiter is one of the key names of the 2017–2025 period. He won repeatedly against different opponents, in different countries and with different vehicle configurations. Four SCL world truck-pull championships separated across six years show recurring dominance rather than one isolated peak. Even after he stopped winning the Dutch title, he continued to take first place in truck pulls at major contests in 2024 and 2025. That is the signature of an athlete who maintained a narrow but highly valuable elite skill for longer than the average strongman competitive window.

Career assessment and sporting legacy

Kelvin de Ruiter's career can be divided into three phases. The first, from 2011 to 2016, was national accumulation, when he learned to turn a very tall frame into a competitive tool. The second, from 2017 through 2023, was the international expansion and peak phase, beginning with the first world truck-pull title and culminating in the 2021 SCL championship, the 2022 WSM appearance and the fourth truck-pull world title in 2023. The third, from 2024 onward, is the longevity phase, with national podiums, an SCL podium and repeated event wins even as his overall placings became less dominant. This structure makes clear that his success did not depend on one exceptional season.

In a sport where absolute records receive most of the attention, de Ruiter represents another form of excellence: durability, extreme specialisation in one event family, and enough versatility to win complete contests. He has not been the greatest log presser of his era, nor the most dominant conventional deadlifter, but the combination of truck pull, carries, yoke, stones and special deadlifts made him especially dangerous in SCL formats. When those components aligned in 2021, he won the league. In Dutch strongman history he therefore remains both a multiple national champion and one of Friesland's most successful international strength-sport exports.

As of late September 2026, his statistical profile remains open rather than closed. Strongman Archives lists him active in 2026, and the Timișoara appearance means retirement should not be declared on the available public evidence. At the same time, a new Dutch generation has taken over the national title, gradually shifting de Ruiter's role from dominant champion toward veteran reference point. That transition is part of the story. The athlete who was eighth nationally in 2011 became, fifteen years later, one of the standards against which newer Dutch strongmen can be measured.

Sources and verification method

This profile was built by cross-checking several categories of source. Strongman Archives serves as the primary reference for contest placings, event results and current competition totals. Giants Live was used for core biographical information, occupation, coaching background and the pathway into strongman. Guinness World Records independently confirms the 670 kg Viking Deadlift achieved on 26 September 2020. The 2021 SCL World Finals and 2023 SCL World Truck Pull Championships were checked against competition databases and SCL-related reporting. KelvinDeRuiter.nl and the athlete's official Linktree confirm public branding and social accounts. RTV NOF, VICE Netherlands, Panorama and regional Dutch journalism were used for context on work, food intake, Big Boss Gym, family history and the personal circumstances around the 2019 national title.

What makes de Ruiter's profile distinctive in recent strongman history

Taken as a whole, de Ruiter's career is a useful example of the different forms of excellence rewarded by modern strongman. Some athletes enter history through one absolute record, others through a short period of major championship dominance, and others through longevity combined with mastery of a particular event family. De Ruiter combines parts of all three. He owns a clearly documented Guinness record, an overall Strongman Champions League title and four national championships, while also possessing one of the most recognisable technical signatures in vehicle pulling. His results are not concentrated into one brief peak. His first Dutch podium came in 2014, his first world truck-pull title in 2017, the SCL championship in 2021, a fourth truck-pull world title in 2023, and major event wins and national podiums continued through 2024 and 2025. Spread across more than a decade, that pattern makes the career more substantial than a simple trophy list can show.

Outside the Netherlands, de Ruiter may be less famous than athletes who won World's Strongest Man, the Arnold Strongman Classic or multiple Giants Live majors. That difference in public recognition should not be confused with a lack of high-level achievement. Strongman Champions League has its own demanding structure, built around repeated stages, extensive travel and changing equipment, surfaces and climates. De Ruiter adapted extremely well to that model. He competed across Europe, the Middle East, the Caribbean, Africa and the United States, progressing from Dutch finals to single-event world championships, then to Giants Live and World's Strongest Man. At the same time, he kept a strong local base in Friesland, a practical trade and a gym built around the specific needs of strongman. That combination of international athlete and working tradesman is central to his identity.

For a historical strongman archive, de Ruiter deserves to be followed not only through titles but through technical development. In 2011, truck pull was already one of his stronger events. By 2017 that quality had developed enough to produce a world title. By 2021 the rest of his event profile had risen high enough for him to win an SCL World Final and the overall league. In 2025, at age 37, he could still deadlift 400 kg in competition and win the truck pull at the Dutch championship. In essence, it is a career about converting a natural advantage into a refined competitive skill and then preserving that skill for years. If 2021 is the overall peak, the full 2011–2026 span is the more complete measure of his sporting career.
