Course DNA
The Course
Silver Moon 100 runs 100 mi through Reedley, California. +3,098 ft gain and -3,098 ft loss. Surfaces skew 100% farm path / dirt road. Mile 85 gate at 24 hours to earn six more. High point near 2,629 ft. Low near 1,333 ft. April temps run 50°F to 75°F. The course rewards patience early and punishes rushed descents after mile 50.
The Work
Train for 3,098 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 Reedley, California: plan for 50°F to 75°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 100% farm path: 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. Mile 85 gate at 24 hours to earn six more 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.
