Le Trail du Buis

Le Trail du Buis, taking place in the town of La Buisse, offers three trail formats: 10 km, 21 km, and a 30 km option, plus a non-competitive 10 km Nordic walk.

The 10 km Course Nature starts from the village hall, covering roughly 400 meters of vertical gain. It begins with an easy flat section before tackling the rolling foothills of Grand Ratz, winding through quaint hamlets and varied terrain. It’s an ideal course for beginners or runners looking for a fast effort.

The 21 km Trail du Buis (solo or duo) gains about 1,000 meters over a mix of steep ascents, forest trails, single-track paths, and farm roads around the Grand Ratz plateau. It’s the event’s signature route and a solid test of both endurance and technical ability.

The 30 km Trail du Buis offers 1,300 meters of ascent as it explores the Grand Ratz via a mix of single track, wooded sections, and ridgeline climbs with sweeping views of the Grande Sure.

Whether you’re chasing a personal best, testing your limits, or simply out to enjoy the trails of the Grand Ratz, the Trail du Buis offers a rewarding experience in a beautiful corner of the Isère.
