Chartreuse Backyard Ultra 2026: Baptiste Dugué wins the race after 35 hours and 234.7 km!

There’s only one left! After 35 hours of racing and 35 laps completed – a total of 234.7 km – Baptiste Dugué is the overall winner of the 2026 Raidlight Chartreuse Backyard Ultra! An incredible finish, as the victory was decided by the narrowest of margins. Baptiste told us he had seriously considered pulling out during that final lap. But when he didn’t come across his last rival on the course, he realised he was now the only one left in the race… and that he had just won this year’s event! 35 hours of effort, 234.7 km and a magnificent victory for Baptiste Dugué. Well done!
