Trail des Crêtes takes place in Dannemarie-sur-Crète, part of the Doubs Terre de Trail calendar and the Challenge Bois Moyne. Participants can choose from two solo distances: 10 km with 290 m elevation gain and 20 km with 540 m, both contributing to the challenge. A 10 km "duo décalé" format is also available, alongside free children's and beginner events incorporating bike-and-run and summer biathlon.
The course follows paths around the village, some of which are opened specifically for the event. Features include old winegrowers’ huts, a botanical trail, streams, springs, single track, and some technical sections. The duo race presents a unique format: one runner begins, followed ten minutes later by the second on the same course. They must reunite at the 9 km mark to complete the final kilometre together. This event, nearing its fifteenth edition, marks the start of the Doubs Terre de Trail calendar.
