The route
The opening section is flat, through Chalamont, Pont-d’Ain and Poncin. The riders then head into the hills of the Bugey, including the Col du Berthiand and the Col de Richemond, before the final climb from Culoz up its famous hairpins. The Tour is no stranger to the Grand Colombier: it has crossed or finished on the mountain several times since 2012.
Watching the race
The Bugey Sud Grand Colombier tourist office says vehicle access will be restricted ahead of the race and encourages spectators to go up on foot or by bike. Maps, times and access rules for the final climb have not been released yet; we will update this article once they are.
The summit is a protected natural area (espace naturel sensible). Stay on the paths, keep dogs well away from grazing herds and take all your litter home.
