A look at XTERRA’s most decorated World Champions, as Arthur Serrières and Solenne Billouin stand on the verge of a historic three-peat.
When the XTERRA World Championship returns to the trails of Trentino for the third time, reigning champions Arthur Serrières and Solenne Billouin will be chasing their third consecutive titles on the biggest stage in off-road triathlon. In the past two years, the French duo have become synonymous with dominance, each racking up more wins than any of their closest rivals. Both thrive under pressure, particularly when the stakes are highest.
But completing the three-peat will be no easy task, as the margins at the top of the sport have become razor-thin since the inception of the World Cup. If either athlete triumphs in Italy on September 28, they will take a giant leap toward securing their legacy as part of an elite group of XTERRA icons—those with three or more World Championship titles.
From the ‘The Scottish Rocket’ who has podiumed in an incredible 10 World Championship races to ‘The Boss’ who got it done on his first attempt, these are the icons who hold more World Championship hardware than any other athlete in the 28-year history of XTERRA off-road triathlon racing.
Julie Dibens of Great Britain rightfully starts the list of XTERRA World Championship icons as the first athlete in the history of the sport to win three consecutive World Championship titles.The three-peat has only been achieved once since the dominant run of Dibens from 2007-2009, but that could change this year with both Arthur Serrières and Solenne Billouin poised to join the club.
Dibens’s reign at the top of the sport was marked by her strength in the water and on the pedals. Before conquering XTERRA, Dibens had a strong background in swimming, representing Great Britain at the 2004 Summer Olympics. Her ability to consistently exit the water in the lead or near the front, followed by powerful bike splits, allowed her to build unassailable leads heading into the run.
Dibens went on to win the 2009 Ironman 70.3 World Championship and finish third at the 2010 Ironman World Championship in Kona, with her passion and impact in triathlon felt long after her iconic three-peat as she continued to contribute to the sport as a coach, mentoring the next generation of champions.
One of the early triple-threat athletes in XTERRA, Spain’s Eneko Llanos combined the swimming and running speed of a triathlon Olympian with unparalleled mountain bike handling skills that saw him become just the fourth athlete in history to join the club of those holding 3 World Championship titles.
An accomplished road triathlete with a distinguished career on the Ironman circuit, Llanos also represented his country at the 2000 and 2004 Olympic Games on his way to becoming one of the most successful athletes in XTERRA history. In 2008, after a second-place finish at the Ironman World Championship in Kona, he placed 6th at the XTERRA World Championship just weeks later. However, he returned in 2009 with a determined performance to claim his third XTERRA World title, tying Conrad Stoltz for the most wins at the time.
Llanos’s versatility and endurance made him one of the most well-rounded athletes in triathlon, both at the time and in history, with his 6 World Championship podiums and 3 World titles being just the start of a period of Spanish dominance in XTERRA as he passed the torch to none other than Ruben Ruzafa.
In a sport that was originally designed to pit road triathletes against specialist riders, it was Melanie McQuaid that would be the first of the dominant Champions to show just how lethal a pro MTB rider can be when over 60% of the race is spent in the dirt and on two wheels.
Before transitioning to triathlon, McQuaid competed at a high level in mountain biking, racing in World Cup events starting in 1998. Though she initially considered triathlon, McQuaid opted to focus on mountain biking, where opportunities were more abundant at the time. But once she discovered the world of XTERRA off-road triathlon, her dominant reign at the top would go on to span a full decade, absent from the World Championship podium on only three occasions between 2000 and 2009.
McQuaid continued to leverage her biking skills in off-road triathlon and Ironman 70.3 events, claiming multiple ITU Cross Triathlon World Championships and 70.3 victories. Similarly to her successor, Julie Dibens, McQuaid’s impact on the sport remained strong as she dedicated herself to coaching and guidance for the next generation of athletes.
Still a force to be reckoned with to this very day, Lesley Paterson remains one of the most inspirational figures in the history of XTERRA.
Nicknamed ‘The Scottish Rocket’ for her remarkable grit and versatility, Paterson's journey to the top was anything but easy. She has faced numerous challenges, including battling Lyme disease, which sidelined her for extended periods. Yet despite these setbacks, she went on to become one of the most decorated World Champions of all time.
Her breakthrough came in 2011, when she captured her first XTERRA World Championship title in Maui, showcasing her exceptional abilities across all three segments of the race. She successfully defended her title in 2012 and continued to be a podium regular all the way through to 2021. One of her most remarkable victories came in 2018, when she overcame Lyme disease to win her third World Championship, proving that her determination and endurance were unmatched.
Outside triathlon, Paterson found even further success as the co-writer and executive producer of the 2022 multiple Oscar-winning All Quiet on the Western Front. Yet despite her busy schedule, she still returned to defend her XTERRA USA Championship title in 2023, in what could only be the perfect illustration of how nothing is impossible in the eyes of the all-time great ‘Scottish Rocket’.
Following in the footsteps of Melanie McQuaid, Ruben Ruzafa exploded onto the scene as the next of the specialist riders to dominate the sport of XTERRA in a reign that lasted for the better part of 16 years. To this day, Ruzafa is regarded as the best rider in XTERRA history and is credited with having single-handedly changed the sport as other athletes were forced to adapt.
Having competed at the highest levels of mountain biking, including multiple national titles and World Cup podiums, Ruzafa made his name known in the XTERRA community faster than anybody else by winning the World Championship in his very first attempt in 2008. So dominant were his riding skills that he soon earned the nickname of ‘The Boss’ as his competitors struggled just to keep his back wheel in sight.
Over the years, few athletes could match his pace, allowing Ruzafa to rack up 9 podium finishes and 4 World titles between 2008 and 2022. Even as younger athletes emerged, Ruzafa remained a formidable competitor, finishing 4th overall in the inaugural XTERRA World Cup in 2023. At the start of 2024, after a stellar 16-year career, Ruzafa announced his retirement, leaving behind a legacy as one of the most decorated and influential athletes in the sport’s history.
Conrad ‘The Caveman’ Stoltz needs little introduction. Still a major figure in the sport, he continues to shape XTERRA as the Race Director of XTERRA South Africa, having brought the sport back to his homeland. Before his off-road dominance, Stoltz was a powerhouse in road triathlon, even representing South Africa at the Sydney 2000 Olympics.
With a mountain biking background forged on the rugged trails of Stellenbosch, South Africa, and a hunger for new challenges outside of road triathlon, Stoltz quickly rose to the front of XTERRA racing. His bike splits became legendary, enabling him to dominate the field and cement his status as one of the most formidable athletes of his era.
Stoltz earned five XTERRA World Championship podiums, with four outright wins between 2001 and 2012. His 2010 victory holds special significance—not only because he dedicated it to his father, who was battling cancer at the time, but also for making history as the first athlete ever to win the XTERRA World Championship on a 29er mountain bike.
No stranger to breaking records, Flora Duffy stands alone at the top of the pile as the single most decorated XTERRA World Champion of all time. Not only does the Bermudian hold a record 6 World titles, she is also the only athlete to have achieved 4 consecutive World Championship wins.
Her dominance in the sport is marked by an unmatched combination of strength in all three disciplines—swim, bike, and run. She often led from the very start of her races, setting the fastest splits across all segments. In her debut XTERRA World Championship in 2014, she overcame a crash on the bike to secure her first title, signalling the start of her reign in off-road triathlon.
Duffy’s XTERRA career is interwoven with her incredible success in other triathlon formats. She is a multiple-time ITU World Champion and made history in 2021 by becoming the first athlete to win Olympic gold, a World Triathlon Championship, and an XTERRA World Championship in the same year. She also holds the honour of delivering her home country of Bermuda with its first-ever Olympic gold medal.
Her career is far from over and she could easily still add to her record numbers had she to add her name to a World Championship start list. But for now, Duffy’s 6 world titles remains the number to beat for the likes of Arthur Serrières and Solenne Billouin as they continue to add to their legacies.
