Course DNA
The Course
Nice Côte d'Azur 100M runs 165 km through Auron to Nice, France. +26,022 ft gain and -31,205 ft loss. Surfaces skew 70% trail / 25% jeep / 5% paved. Cabane des Chasseurs and the Venanson to Utelle ridge. High point near 8,766 ft. Low near 21 ft. September temps run 50°F to 90°F. The course rewards patience early and punishes rushed descents after mile 51.
The Work
Train for 26,022 feet of climbing across 165 km. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 50 hours total means limited margin: rehearse fueling every 45 to 60 minutes and downhill eccentric work weekly. Technicality 5/10. Build a block that simulates the crux near mile 67.
Kit
September in Auron to Nice, France: plan for 50°F to 90°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 50 hours pushes past dark. Poles help on sustained climbs above mile 26. Vest capacity for 2 liters minimum. Shoes matched to 70% trail: lugs for mud, rock plate if the course turns technical after mile 51.
Race Day
Hold effort through mile 26. The field often splits on the first big climb after mile 51. Cabane des Chasseurs and the Venanson to Utelle ridge near mile 67 is where time is won or lost. Walk the steep pinches. Run the flats and gentle downhills. Crew at major aids: socks, calories, ice if hot. Transitions under 5 minutes when possible. Final third is 34 miles of fatigue management. Finish with reserve for the last descent.
