Raidlight Trail Festival: the trail running celebration in the heart of Chartreuse

The Raidlight Trail Festival is one of the major trail running events in Isère and the Auvergne-Rhône-Alpes region. Every year in May, the village of Saint-Pierre-de-Chartreuse welcomes up to 1,800 runners from all over France and Europe for a weekend of mountain races in the exceptional setting of the Chartreuse Regional Natural Park.

Six race formats for all levels

An exceptional natural setting

The Raidlight Trail Festival courses wind through fir and spruce forests, alpine pastures, and limestone ridges of the Chartreuse massif. Runners evolve in a preserved environment, classified Natura 2000, between peaks culminating at over 2,000 meters and green valleys, offering breathtaking panoramas of the Alps, Mont Blanc, and the Belledonne range.

A festive and family-friendly spirit

Beyond the competition, the Raidlight Trail Festival stands out for its friendly and festive atmosphere. The start-finish village offers entertainment, a catering area, and an exhibitors' zone. The Festi'Rando offers a non-competitive alternative (10 €) to discover the trails by walking.

An event rooted in the territory

The festival is organized by Trail Nature Organisation and bears the name of Raidlight, an emblematic trail brand founded by Benoît Laval in Saint-Pierre-de-Chartreuse. The event benefits from the support of the Chartreuse Regional Natural Park, the municipality, and local tourism and mountain sports stakeholders, contributing to the renown of Chartreuse as a leading trail destination.
