The Trail de Pleyben begins and concludes at Gymnase Pierre Cloarec in Pleyben, Finistère, offering four trail races. Organized by APEL Saint Joseph de Pleyben, this event marks its 21st year and serves as the concluding stage of the Challenge Armorik Trail. The primary Canal PopKorn race covers 44.5 km with 1,250 m of elevation gain, intended for experienced, well-prepared runners, not novices.
The long course departs Pleyben via local paths and woodland tracks, descending towards the Nantes-Brest Canal and its towpath. It continues past Pont-Coblant before proceeding through Gouézec to Roche du Feu, reaching an altitude of 281 m. Following a swift, technical wooded descent back towards the canal, participants will pass the Victor, a navigational monument, then ascend towards Pleyben on trails through Lennon. The course combines technical terrain, runnable sections, ascents, and descents. A two-person Canal PopKorn relay divides the distance into 18.5 km and 26 km segments, with a limit of 50 teams.
