Les Foulées de Longemer 12 km is a morning road race in Xonrupt-Longemer, Vosges, Grand Est, France. The 12 km runners begin at 9:30 AM, starting with the 6 km field. A handisport race departs just before them, and children's races follow later in the morning. This event is part of a small race-day program, not a standalone long-distance race.
The route follows a lake format: 12 km runners must reach the finish-area checkpoint to start their second lap of the lake; otherwise, they are stopped there. The event's distance has varied across editions, including 6 km, 10 km, and 12 km formats. Vosges Course a Pied manages the timing. The setup includes live GPS tracking, a fan zone within the app, awards for the top three male and female finishers, and a souvenir gift for the first 200 finishers in the 12 km race.
