Marine Corps Marathon Wheelchair: Guérin Owns the Course Solo

• Sole finisher: Thibault Guérin completed the full 26.2-mile course in 4:18:52, averaging 9:52 per mile.
• Wire-to-wire: Guérin held 1st place at every checkpoint from start to finish — never challenged, never headed.
• Fastest segment: His 5K→10K split was the fastest among the men — though with no one to race, he was setting the standard entirely on his own terms.

On a crisp October morning in Arlington — 43°F, a light 6 mph breeze, and heavy humidity hanging in the air — Thibault Guérin of Saint Jouan Des Guerets rolled out ahead of the main field and never looked back. In the men's wheelchair race, he was the only competitor on the course, and he handled the iconic 26.2-mile loop through Washington D.C. and Arlington with complete command from the opening miles.

Guérin led at every single checkpoint — a clean sweep from gun to tape — and posted his sharpest effort on the 5K-to-10K stretch, where he recorded the fastest men's split of that segment. Whether that burst was a deliberate push or simply finding his rhythm on a familiar stretch of the course, the data shows it was his quickest passage of the day.

Crossing in 4:18:52, Guérin becomes the men's wheelchair champion of the 2025 Marine Corps Marathon. Racing alone strips away the drama of head-to-head competition, but it demands something different — self-motivation, pacing discipline, and the resolve to push through 26.2 miles with no one to chase and no one chasing you. By that measure, Guérin delivered exactly what was asked of him.
