The Hardloop Trail d'Annecy Les Glaisins begins at the Glaisins park and gymnasium in Annecy-le-Vieux, situated above Lake Annecy. This spring trail-running event features nine races, attracting over 2,100 participants and a substantial team of volunteers from local clubs.
The event offers a variety of races, from shorter trail runs to more demanding mountain courses. Distances include 10 km, 23 km, and approximately 36-37 km, with the longest route involving an ascent of around 2,400 metres. Dedicated races are available for children, and the City Trail Duo allows two runners to compete as a pair. Annecy Athlétisme and Annecy CSAV Handball jointly organize the event, with some races holding French Championship qualifying status under an FFA Trail Bronze label.
