Kodiak Ultra Marathons by UTMB 2026

2025·2026

Friday, October 9, 2026 at 1:00 PM GMT-7

The 2026 routes are pending approval by the US Forest Service, and the race says minor changes could be made before race day to avoid hazard areas. The 100 Mile's aid-station chart and cutoffs were re-drawn for 2026; the shorter races still carry their 2025 charts.

Sold out.
