Cold start — layer up, big temp swing

Runners will start in chilly 36°F conditions — dress in layers for the corral and plan to shed early. Temps will climb significantly to 66°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

The Jackson Hole Marathon races cover the best of the Jackson Hole Valley and finish at the base of the Teton Mountain Range in Teton Village. If the altitude doesn’t take your breath away, the scenery certainly will! While you’re here, enjoy Jackson’s vibrant food and art scene, sample some of the best craft breweries in the country, and explore endless open space in the Bridger-Teton National Forest, and Grand Teton and Yellowstone National Parks.
