Top of Tamarack

Lace up for a profoundly impactful experience at the Top of Tamarack, an inspiring running, hiking, and biking event held on Saturday, September 26, 2026, in the scenic surroundings of Donnelly, ID. This unique race is more than just a physical challenge; it's a powerful statement for mental health awareness and suicide prevention, celebrating resilience and honoring those affected by mental health struggles. The course is an out-and-back journey along gravel service roads that ascend Tamarack Mountain, offering breathtaking views of Valley County as you climb. Participants can choose their own challenge, tackling any distance up to the maximum 15-mile round trip, which includes a formidable 2,900-foot elevation gain to the summit.

The Top of Tamarack stands out with its encouraging "no DNF" philosophy, focusing on personal achievement rather than just competitive finishes. Each mile to the summit is marked, and participants collect special tokens along the way, serving as tangible reminders of their "mental strength." Those aiming for the top can collect all eight tokens at the summit aid station. The event fosters a supportive atmosphere, encouraging athletes of all levels to push their limits for a great cause. Expect typical race day conditions in late September to be crisp and clear, with highs around 67F and lows around 34F, and only an 8% chance of precipitation, providing ideal weather for a challenging ascent. The race begins at Tamarack Village, with convenient parking nearby, and concludes at the same spot after your triumphant descent. Top finishers in both running and biking categories will be crowned King and Queen of the Mountain.
