The Les Arcs Star Trail is an 11 km evening trail race held at Arc 1800 within the Bourg-Saint-Maurice–Les Arcs ski area. It takes place on a groomed snow slope, distinct from typical mountain paths. The race begins at 18:00, requiring participants to use headlamps from the outset. The course covers 500 m of elevation gain over its short length. The entry fee is set at 7 EUR.
The route leads participants to an aid station at 5.4 km in Arc 1600, offering hot and cold food, along with liquid and solid provisions, before a 19:00 cutoff. After finishing, participants can find refreshments indoors at the Belambra hotel's congress hall. Awards are scheduled for 20:00. The Bourg Saint Maurice Les Arcs tourist office organizes the event, which has seen its field grow from a small number to over 300 participants.
