The Ultra-Trail Cote d'Azur Mercantour (UTCAM) is a 120km UTMB Index mountain ultra starting and finishing in Saint Martin Vesubie, within the Mercantour National Park of the French Riviera hinterland. The course gains 7,800m D+ over 120km -- 65.0 m/km elevation density, above UTMB's 56.9 m/km -- with a 34-hour time limit and a 5:00 AM start on July 4. Founded in 2022, the UTCAM is a UTMB Index 100M race requiring qualification through a race-specific points system (80 points from a qualifying race completed between January 2023 and June 2026).
The course leaves almost no room to recover: 44.1% uphill, 14.0% flat, 41.9% downhill, with 14.8 km of ascending at 20%+ gradient across the full 120km. The race's defining sequence arrives in the final third: two back-to-back major climbs at km 79.68 (1,208m over 10.8 km, 11.2% avg) and km 94.53 (925m over 5.0 km, 18.5% avg), followed by the final descent -- 1,366m over 7.0 km at -19.5% average gradient into the finish. The -19.5% average on the closing descent is UPPER-tier extreme, arriving on legs that have already covered 113km and two major climbs.
Nice-Cote d'Azur Airport (NCE) is 63 minutes from the start. For international runners, the combination of Riviera access, Mercantour wilderness, and UTMB-surpassing elevation density makes UTCAM one of the most technically demanding and logistically accessible 120km races in Europe.
