100K: A REDESIGNED ROUTE FOR 2025
With just four months to go until the 4th edition of Nice Côte d’Azur by UTMB® (25–28 September 2025), organisers have unveiled a major update to the 100K route.
The first 40km between Roubion and Brec d’Utelle has been completely reworked. This wilder and more technical new section will take runners through the villages of Ilonse, Bairols, Tournefort and La Tour, offering a more immersive experience in unspoilt natural surroundings. The overall total elevation gain has increased to 5,152m D+ (+ 600m), and the time limit has been extended to 30 hours.
2025 REGISTRATION:
FINAL SPOTS REMAINING FOR THE 100M
The 20K, 50K and 100K races are now fully booked.
Only a limited number of places remain for the flagship 100M format, which sets off from Auron at 13:00 on Friday 26 September. This 159km challenge, featuring 8,200m of elevation gain, takes runners deep into the Southern Alps and finishes in spectacular style on Nice’s fabled Promenade des Anglais.
