Course DNA

The Course

Living Adaptive 100 runs 100 mi through Las Vegas, Nevada. +801 ft gain and -801 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 50.

The Work

Train for 801 feet of climbing across 100 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 65.

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 25. Vest capacity for 2 liters minimum. Shoes matched to 60% road: 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. Miles 90 to 100 when the lower limbs lock up 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.
