The Trail de l'Odet is a trail running series held in the Odet region of Brittany, organized by the Erge Vras Court club. Participants can choose from three running distances: a discovery route, a short route, and a long route. A walking option is also available for those who wish to participate without competing.
The event has a history spanning over twenty years, with results archived for more than two decades. Recent results are categorized by distance. The race is part of the Challenge Armor-Argoat, and awards are detailed on the event website. A company challenge category has been offered, attracting club runners, local participants, workplace teams, walkers, and first-time trail runners.
