The Tour de Ballainvilliers is a road race held in October in Ballainvilliers, a town within the Essonne department of Île-de-France, France. Participants can select between a 5 km or 10 km race, with additional events for children and juniors. The 10 km distance is the most frequently chosen.
Both adult races follow a town-course road route, with the 5 km and 10 km each comprising a single loop. The event contributes to a charitable cause, utilizes ADEOCHRONO electronic timing, and provides app-based live GPS tracking, allowing spectators to follow runners in real time and access a fan zone feature.
