The Trail Running Festival takes place at Petit Port in Annecy Le Vieux, near Annecy. It is structured as a spring trail-running day, not a single race. The event is designed for beginners, regular trail runners, families, and individuals interested in learning about the sport through running, gear testing, and discussions with people in trail running.
The schedule features group runs led by athletes, social runs, challenges, athlete interviews, conferences, and workshops. A brand village provides a space for runners to interact directly with brands and test products under real conditions on marked routes. Activities are available for children, and the day also includes a tombola, food, and drinks, making it function as a community gathering as well as a running event.
