Jackson Hole Marathon
Race Day Weather
Cool start, warming up, tailwinds ahead
Runners will face a chilly start at 35°F, feeling closer to 33°F during pre-race warm-ups. As temperatures rise to 62°F, they'll encounter a mild headwind between miles 5-8, making pacing adjustments necessary for those sensitive to wind. A favorable tailwind from miles 11 to 26 will aid runners as they navigate the gently rolling terrain, so they should conserve energy early and push during the later segments.

Race Info
The Jackson Hole Marathon starts at the historic elk antler arch on Jackson Town Square, passes the National Elk Refuge, and follows the community pathway system around the South Park Loop before crossing the Snake River near mile 17. The USATF-certified, Boston-qualifying course finishes at the elk antler arch in Teton Village at the base of the Tetons, run almost entirely above 6,000 feet elevation. The same race weekend includes the Hole Half Marathon and Quarter Marathon, ending with a community Oktoberfest celebration in Teton Village. Jackson sits near the Bridger-Teton National Forest and Grand Teton and Yellowstone National Parks.
