Matthieu Bonne Breaks Iconic 48-Hour World Record with 485.099 Kilometers

Pabianice, Poland – June 1, 2025

In a performance that has instantly entered the history books, Belgian ultra-endurance athlete Matthieu Bonne has shattered one of the most revered records in long-distance running. At the GOMU 48-Hour World Championship in Pabianice, Poland, Bonne ran a staggering 485.099 kilometers, setting a new official world record in the 48-hour category — a feat once considered untouchable.

Ending a 30-Year Reign

The previous benchmark of 473.5 kilometers, set in 1996 by Greek ultrarunning legend Yiannis Kouros, had stood unchallenged for nearly three decades. Kouros' record was seen by many in the sport as a mythical ceiling — the kind of limit that defines an era. Until now.

With his 2025 performance, Bonne not only surpassed this legendary mark, but also broke through the symbolic 300-mile barrier, a milestone few thought achievable in a single continuous effort.

A New Era for Ultrarunning

Bonne’s achievement reverberated far beyond the track in Poland. The 48-hour record is widely regarded as one of the ultimate tests of human endurance — a blend of physical resilience, pacing precision, sleep deprivation, and psychological grit. For many ultra-athletes, even completing 48 hours of continuous running is a triumph. To cover 485 kilometers within that time is something else entirely.

The performance has already garnered global attention across the ultrarunning community and international press. It marks not only a personal best for Bonne, but a defining moment for Belgian sport — positioning him as one of the most elite ultrarunners of his generation.

From Setback to Supremacy

Bonne’s journey to this achievement has not been linear. Earlier this year, he attempted the same record at a race in Taiwan but was forced to withdraw due to a respiratory infection. That setback became fuel for his comeback. With renewed focus and a meticulously executed training program, Bonne arrived in Poland stronger, sharper, and fully prepared to take on the challenge.

His successful attempt was backed by a high-performance support crew focused on nutrition, pacing, hydration, and recovery — all critical components in such a precise, high-stakes environment.

Powered by Partners, Built on Belief

Bonne’s world record was not achieved alone. A dedicated group of partners stood behind him — brands and individuals who believed in the vision, trusted the process, and provided the support needed to pursue such an ambitious goal. Their backing made it possible to prepare, travel, and perform at the highest level.

Without their support, this historic achievement would not have been possible.

More to Come

Though this world record stands as a monumental milestone, it is by no means the final chapter. Bonne has made it clear that new challenges lie ahead, with preparations already underway for the next phase in his extraordinary journey. As always, these future goals will demand the same intensity, discipline, and belief that made this 48-hour record possible.

Conclusion: History Made in Pabianice

Matthieu Bonne's 485.099 kilometers over 48 hours is more than just a number — it’s a redefining moment in the sport of ultrarunning. It marks the end of an era ruled by Kouros, and the start of a new chapter led by a determined athlete from West Flanders, Belgium.

In a discipline where limits are constantly tested, Matthieu Bonne has proven one thing:

even the most legendary records are made to be broken.
