Course DNA
The Course
Gorge Waterfalls 100K runs 62 mi through Cascade Locks, Oregon. +6,427 ft gain and -6,427 ft loss. Surfaces skew 70% singletrack / 20% paved path / 10% dirt road. Out-and-back waterfall miles before the Wyeth climb. High point near 1,506 ft. Low near 65 ft. April temps run 40°F to 65°F. The course rewards patience early and punishes rushed descents after mile 31.
The Work
Train for 6,427 feet of climbing across 62 mi. Back-to-back long runs on similar surfaces. Practice power-hiking grades above 15 percent. 17 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 40.
Kit
April in Cascade Locks, Oregon: plan for 40°F to 65°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 17 hours pushes past dark. Poles help on sustained climbs above mile 16. Vest capacity for 2 liters minimum. Shoes matched to 70% singletrack: lugs for mud, rock plate if the course turns technical after mile 31.
Race Day
Hold effort through mile 16. The field often splits on the first big climb after mile 31. Out-and-back waterfall miles before the Wyeth climb near mile 40 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 20 miles of fatigue management. Finish with reserve for the last descent.
