Lavy des Cimes sends runners directly up the mountain from Viuz-la-Chiésaz, a village near Annecy in Haute-Savoie. This December mountain-running series centers on a vertical kilometer, where the task is straightforward and demanding: gain approximately 1,000 meters as quickly as possible. The primary uphill race covers about 4.6 to 4.7 km. Additionally, the family aspect of the event includes a 1.9 km Funky Trail for children and pairs, a short Funky Vertical, and a biathlon introduction for ages 10 and up.
The courses traverse the slopes above the village, offering views toward the Aravis, the Bauges, and Mont Blanc when conditions permit. The race originated in memory of Gaël, and this founding principle continues to influence the event. It serves not only as a challenging climb for specialists but also as a community day for families, young runners, mountain enthusiasts, and individuals seeking a brisk winter exertion. The Funky Trail and Funky Vertical have been established components for some time, and the first Saturday in December is integral to the race's established schedule.
