Course DNA
The Course
The Canyons 100 runs 100 mi through Auburn, California. +13,020 ft gain and -16,769 ft loss. Surfaces skew 90% singletrack / 10% dirt road. Back-to-back canyon nights after Cal Street. High point near 5,016 ft. Low near 593 ft. April temps run 40°F to 95°F. The course rewards patience early and punishes rushed descents after mile 50.
The Work
Train for 13,020 feet of climbing across 100 mi. Back-to-back long runs on similar surfaces. Practice power-hiking grades above 15 percent. 30 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 65.
Kit
April in Auburn, California: plan for 40°F to 95°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 30 hours pushes past dark. Poles help on sustained climbs above mile 25. Vest capacity for 2 liters minimum. Shoes matched to 90% singletrack: lugs for mud, rock plate if the course turns technical after mile 50.
Race Day
Hold effort through mile 25. The field often splits on the first big climb after mile 50. Back-to-back canyon nights after Cal Street near mile 65 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 33 miles of fatigue management. Finish with reserve for the last descent.
