Les Foulées des Thermes is a local race series in Forges-les-Bains, Essonne, southwest of Paris, organized annually by Ouest Essonne Athlétisme. It focuses on road and trail running, offering multiple courses including a children's race. The walking option is part of the Essonne Nordic walking challenge.
The series also features Les Foulées des Thermes by Night, a night trail event with two distance options and a race village at the Centre socioculturel on rue de l'Église. The event emphasizes practicality and community: a food truck is available for attendees, participants are encouraged to bring an eco-cup, and the Didier Verraz Challenge benefits Carrefour Des Solidarités, supporting families in Limours and surrounding areas through online donations and on-site sales of refreshments.
