The route typically loops around Plouay and the surrounding Morbihan countryside, using a combination of short climbs, narrow roads, and exposed sections where crosswinds can split the field. The finish circuit is usually raced multiple times, with the Ty Marrec and Côte de Lann Vrihan climbs appearing repeatedly in the closing laps. These aren't long enough to drop pure sprinters outright, but they're steep and frequent enough to thin the group and reward riders who can accelerate out of corners and recover quickly. The race is often won by a small group or a late attacker who reads the final-lap positioning correctly. Pure sprinters can survive if the wind stays calm and the pace stays controlled, but the course design favors puncheurs and riders comfortable in messy, attritional finales.
Circuit attrition
Eight laps of a demanding 27 km circuit plus a shorter finishing lap, totaling roughly 247 km. The repeated climbs accumulate fatigue and thin the field through pure attrition.
Breton weather
Rain, wind, and unpredictable conditions are constants in late-August Brittany. The weather often plays as decisive a role as the terrain.
Punchy climbs, not mountains
The Cote du Lezot (1 km at 6%) and Cote de Ty Marrec (max 10%) reward repeated accelerations over sustained climbing power.
