Course DNA
The Course
Autumn runs 100 mi through England. +12,507 ft gain and -12,510 ft loss. Surfaces skew 70% trail / 20% path / 10% road. Moorland bogs, steep fells, and night navigation on unmarked paths. High point near 748 ft. Low near 59 ft. October temps run 40°F to 70°F. The course rewards patience early and punishes rushed descents after mile 50.
The Work
Train for 12,507 feet of climbing across 100 mi. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 28 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
October in England: plan for 40°F to 70°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 28 hours pushes past dark. Poles help on sustained climbs above mile 25. Vest capacity for 2 liters minimum. Shoes matched to 70% trail: 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. Moorland bogs, steep fells, and night navigation on unmarked paths 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.
