Les Boucles du Steir was a city road event in Quimper, Finistère, Brittany. Scheduled for mid-February, it featured a 10 km road race and two walking events, catering to both runners and walkers, not exclusively competitive road racers.
The 10 km run followed a single 10 km loop through Quimper’s streets. Walkers could select the same 10 km loop or a shorter 5 km loop. A past edition attracted over 500 participants. The event is no longer held; it was succeeded by the Ar Meilhou Glaz Trail, which continues a race presence in the city with a different format.
