Run In Chambourcy

Run In Chambourcy is a community road-running event held in Chambourcy (Yvelines), organised by ASM Chambourcy. The event on 5 July 2026 offers three distances—10 km, 5 km and a 2 km childrens race—with separate start times for each category and on-site bib collection the day before and on race morning. Races are staged from the Complexe sportif Georges Gallienne, and the event welcomes club and group registrations as well as volunteers to support race-day operations.

The 10 km and 5 km races form part of the Challenge des Yvelines and feature a hilly, undulating on-road course that tests runners strength and pace. Practical amenities confirmed by the organiser include a free secure bag drop, finish-area refreshments and at least one aid station on the 10 km course; showers and changing rooms are not available. Entry and official timing are managed through the listed registration/timing partner, and the organiser provides a contact email for questions and group sign-ups.
