Coteaux et Vallées - Chilly-Mazarin 2026

Coteaux et Vallées is a one-day cycling event held at the Jesse Owens sports center in Chilly-Mazarin, within France's Essonne department. It focuses on road and gravel rides, not a single race distance. Entry is 4 EUR for licensed adults and young riders. The road options include distances of 40 km, 60 km, 65 km, and 85 km, with shorter routes of 20 km and 45 km also listed. Most road routes are designated as easier blue-level rides. However, the longest road option and the gravel route are marked red, allowing participants to select between a more relaxed club-rally outing or a challenging day on mixed surfaces. VCBS organizes the event, and their official club site is vcbs.fr.
