Le Relais de Gars'Z'elles features a 20 km race in Fontaine-le-Comte, Vienne department, western France. The main distance is available solo or as a 2 x 10 km relay. Les Gars'Z'Elles Fontenoises organizes the event in late June, which also includes a 7.5 km race and a 10 km walk.
The route consists of a single 20 km circuit, with relay teams dividing the course into two 10 km segments. The 20 km race is for adults. The relay, shorter race, and walk are open to participants aged 16 and older, requiring parental authorization if necessary. In its seventh edition, the event attracted over 510 participants. It originated from a local running group that convenes Sunday mornings and Wednesday evenings at the Fontaine-le-Comte town hall, offering coached strength training on Friday nights and organizing excursions roughly every two months to explore routes beyond the commune.
