Les 10 km de Trévoux is an evening urban trail race held at the Bas Port in Trévoux, featuring adult events of 5 km, 10 km, and 21 km. All three races commence at 19:30, with participants starting as daylight fades. The event also offers a children’s race and a 10 km walk, which allows for a flexible start between 16:00 and 18:00.
The routes are not flat; the 5 km includes 68 metres of elevation gain, the 10 km has 230 metres, and the 21 km involves 413 metres of climbing. Participants must be self-sufficient as refreshments are available only at the finish. Adult race registration is exclusively online until the Friday preceding the event, while walkers may register on site. AJT Saône Vallée is the organizer, and minors are required to submit a health questionnaire.
