The Course
Nike ACG Ultra-Trail Chongli runs 168 km through China. +10,074 ft gain and -10,139 ft loss. Surfaces skew 75% trail / 20% dirt road / 5% paved. Humid climbs, ridge exposure, and aid gaps in remote terrain. High point near 6,905 ft. Low near 6,612 ft. July temps run 50°F to 85°F. The course rewards patience early and punishes rushed descents after mile 52.
The Work
Train for 10,074 feet of climbing across 168 km. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 38 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 68.
Kit
July in China: plan for 50°F to 85°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 38 hours pushes past dark. Poles help on sustained climbs above mile 26. Vest capacity for 2 liters minimum. Shoes matched to 75% trail: lugs for mud, rock plate if the course turns technical after mile 52.
Race Day
Hold effort through mile 26. The field often splits on the first big climb after mile 52. Humid climbs, ridge exposure, and aid gaps in remote terrain near mile 68 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.
