The Trail de Noel by Rossignol begins at Le Signal in Hauteluce, situated above Les Saisies. Participants can choose between a 10 km or 20 km snow run. The shorter route covers 350 m of elevation gain and is accessible to those aged 14 and older. The longer route, intended for adults, features 790 m of climbing. This winter trail race takes place on prepared paths, with the 20 km participants starting just ahead of the 10 km runners. The Office de Tourisme des Saisies organizes the event, which is contingent on appropriate mountain weather conditions.
The route follows the training paths used by Olympic biathletes Justine Braisaz and Julia Simon, leading participants towards the Bisanne climb. Along the course, runners are treated to vistas of Les Saisies, surrounding mountains, and Mont Blanc. The race embraces its Yuletide theme with decorations, garlands, carols, costumes, and an award for the most festive attire. Bib collection is available in Albertville prior to the event or at Le Signal on race morning. A group warm-up session precedes the start, and a meal and awards ceremony conclude the day's festivities.
