100 Boucles Gravel de la Monnerie (24H)

The 100 Boucles Gravel de la Monnerie is a 24-hour gravel endurance event organised by Cyclo-Sport Fléchois around the Lacs de la Monnerie in La Flèche, in France's Sarthe department. The 2026 edition starts on Saturday 27 June at 1:00 PM, with solo riders and relay teams aiming to complete as many laps of a 7.4 km circuit as possible. The loop mixes a short paved section, a grassy climb of the lake hill with panoramic views and a rolling gravel section, and the weekend programme also includes shorter Découverte, Défi, Nocturne and Matinale formats.
