La foulée verte is a one-hour team relay in Chambéry, held within Parc de Buisson Rond. Teams of two alternate running a 1 km loop, aiming to complete as many laps as possible within the hour.
The loop follows park paths, forest tracks, and undergrowth, offering a natural setting distinct from road races. A 6 km walk is also available for those seeking the same environment without the competition, accommodating pairs of friends, families, runners, and walkers.
