Living Adaptive 100
Las Vegas roads and trails. Scott Davidson's hundred-mile route. More vert and harder surfaces than Jackpot. Proof that adaptive running has no ceiling.

Course DNA
The Course
Living Adaptive 100 runs 23.6 mi through Las Vegas, Nevada. +830 ft gain and -830 ft loss. Surfaces skew 60% road / 40% trail. Miles 90 to 100 when the lower limbs lock up. High point near 2,897 ft. Low near 2,122 ft. March temps run 45°F to 85°F. The course rewards patience early and punishes rushed descents after mile 12.
The Work
Train for 830 feet of climbing across 23.6 mi. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 48 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 15.
Kit
March in Las Vegas, Nevada: plan for 45°F to 85°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 48 hours pushes past dark. Poles help on sustained climbs above mile 6. Vest capacity for 2 liters minimum. Shoes matched to 60% road: lugs for mud, rock plate if the course turns technical after mile 12.
Race Day
Hold effort through mile 6. The field often splits on the first big climb after mile 12. Miles 90 to 100 when the lower limbs lock up near mile 15 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 8 miles of fatigue management. Finish with reserve for the last descent.
