Runners on Tréompan beach


Trail en Iroise

Trail running in Iroise takes place on 6 signposted routes, where the iodized air galvanizes runners. All year round, nature races bring enthusiasts together. Come and try your hand at this sport, and why not prepare for the Trail du Bout du Monde!

About us

Like hiking, running and cycling, trail running can be practised independently. However, the proposals presented here are aimed at experienced trail runners who have been given a positive medical opinion for the activity. All participants are responsible for their own safety (hydration, sun protection, nutrition, technical commitment, highway code). Let's get together and give priority to riders and walkers.

Tour de l'aber Ildut

In the meandering estuary

Between Plouarzel and Lanildut, this 12.9 km circuit is the most maritime and the most poetic: take the ferry to cross the Aber, then walk along the sea in wooded surroundings until you return to your starting point.
