Course à pied nature Villiers-Charlemagne 2027

La Caropolitaine is a nature-running event in Villiers-Charlemagne, in Mayenne, with trail races over 10 km and 20 km. The race listings put the Villiers-Charlemagne nature run in January, and another listing adds 7 km and 14 km options priced at 10 EUR. The day is built for more than trail runners: there is also a 10 km hike and children’s races over 2 km and 4 km. The event has drawn 500 starters and sold out three weeks ahead, with organisers saying it was the first time entries had filled that quickly. Runners mention the good atmosphere and the unusual course as part of the appeal.
