The Course
The Canyons 100K runs 100K through Auburn, California. +9,542 ft gain and -13,291 ft loss. Surfaces skew 90% singletrack / 10% dirt road. Deadwood double visit and Cal Street climb to Foresthill. High point near 5,016 ft. Low near 581 ft. April temps run 40°F to 90°F. The course rewards patience early and punishes rushed descents after mile 50.
The Work
Train for 9,542 feet of climbing across 100K. Back-to-back long runs on similar surfaces. Practice power-hiking grades above 15 percent. 20 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 90°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 20 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
