M50-54 at UTMB Mont-Blanc: Jachymiak Surges Late to Claim the Crown

• Robert Jachymiak wins in 14:10:21 (12:40/mi avg), the only finisher in M50-54 to break 14:15 across 108 km and 6,200 m+ of climbing.
• Second and third separated by just two seconds: Ruben Rodriguez Herrero (14:20:30) edged Nicolas Buys (14:20:32) for the runner-up spot — the places differ, the margin is a sliver.
• Jachymiak's decisive surge: he moved from 162nd among men at the first checkpoint all the way to 81st by the finish, with a 64th-fastest men's split on the Les Tseppes→Vallorcine Entrée segment powering the charge.
• 126 finishers completed the course in M50-54, with the top four all finishing under 15 hours and a nearly 39-minute gap separating 4th from 5th.

Robert Jachymiak, 50, didn't lead this race from the front. Through the early checkpoints he sat outside the top 160 among men — patient, measured, conserving. Then came the turn. Segment by segment he climbed the leaderboard, posting the 64th-fastest men's split on the Les Tseppes→Vallorcine Entrée stretch and arriving in Chamonix in 14:10:21. That's a 12:40/mi average across a course that threads through Italy, Switzerland, and France with over 6,200 meters of ascent — a performance that left the rest of M50-54 firmly in his wake.

Behind him, the battle for second was one of the closest finishes of the entire field. Ruben Rodriguez Herrero and Nicolas Buys ran nearly the same race in aggregate — both clocking 14:20 — but the timing tape tells the real story: Herrero (14:20:30) held off Buys (14:20:32) by two seconds. What makes it richer is that both men ran strong Trient→Les Tseppes segments, Herrero posting the 65th-fastest men's split and Buys the 60th. Buys actually ran that stretch a touch quicker, closing hard — but Herrero had built just enough of a cushion earlier to hold on. Buys, 54, earns a particularly notable podium as the oldest of the top three.

Insik Lee, also 50, rounded out the top four in 14:59:25, climbing steadily from 272nd among men at the first checkpoint to 115th at the finish — the biggest positional climb in the group. Fifth through tenth saw Josef Gruber (16:05:47), Alexandre Vanel (16:39:56), and Gregory Firth (16:43:25) lead a wave of finishers spread across a wide but hard-earned range of times, all of them completing one of ultrarunning's most demanding point-to-point courses before the 28-hour cutoff.
