La Toul an Dour - Milizac-Guipronvel 2026

La Toul an Dour is a trail-running event in Milizac-Guipronvel, Finistère, Brittany, usually held in early October. Runners can choose between trail distances around 8-10 km and 17-18 km, and there is also a nature walk for those who want the route without racing. The course access is notable: about 95% of the route uses paths opened only for the race. The organizers designed the event around the little-seen countryside of Guipronvel, with demanding trails rather than road running. The race has appeared on the official off-road calendar since 2009. Previous editions drew just over 100 participants, suggesting it is a local Breton trail day for runners and walkers rather than a large destination race.
