The 12 km Trail du Grand Genève begins at 09:30 in Etrembières, on the French side of the Geneva area. This is a short trail race with 120 meters of elevation gain, suitable for runners seeking off-road terrain without the commitment of the longer 25 km or 40 km options. The main Trail du Grand Genève event spans two days and also offers walking events.
The event takes advantage of its cross-border location around Greater Geneva, with routes crossing landscapes between France and Switzerland. The program includes 1 km, 8 km, 12 km, 25 km, and 40 km races, along with categories for adults, teams, parents and children, and children. Now in its second edition, the event's format is designed for families and regular runners, as well as experienced trail racers.
