The Yeti 100 Mile Endurance Run

The Yeti 100 Mile Endurance Run is held in Abingdon, Virginia, on October 9, 2026, with a 7:00 a.m. start. It is a single-format trail event, a 100 Miler (160.9 km), organized by Yeti Trail Runners.

One hundred miles is a distance that asks for both physical preparation and a solid plan for the low moments that will come in the night. This race is a natural next step if you have finished a 50-miler or a 100K and want to move up, and a single-distance start keeps the logistics straightforward. Build toward it with a 20-week program: weekly long runs growing to 30 miles or more, back-to-back weekend runs to train tired legs, and at least one night run to practice with a headlamp. Work on a fueling strategy of 200 to 300 calories per hour that you have tested in training, and settle on shoes, socks and anti-chafing products well before October. Having a crew or drop-bag plan will make the second half of the race considerably easier.
