The Trail de la Vallée des Moulins is a Sunday trail-running event in Lanhouarneau, with about 1,400 participants across several formats. Runners can select a 10 km solo race, a 10 km duo, or a 20 km trail, and walkers have a 10 km option. This event is in its twelfth edition, establishing it as a regular fixture for local runners.
The route begins with a quick pace on undulating terrain, then becomes challenging early on: Marina Crenn, the first woman over 10 km, noted it started to hurt around the fourth kilometer. The longer race combines sections that can be run with steep, difficult climbs, enough to test experienced runners; Luca Desmares, a past 20 km winner, took third place after Yann Botrel broke away halfway. Yann Botrel won the men's 20 km, Célia Lareur won the women's 20 km, and Sébastien Bergot, who often serves as the race announcer, exchanged the microphone for a spot in the 10 km duo.
