Welcome to Idaho Running Day! We are Boise's premier athletic race here in the Treasure Valley. Featuring distances from our full marathon, 1/2 marathon, 10K, and 5k distances, we offer everything a runner could need. Idaho Running Day is a Boston qualifying event hosted on the beautiful Boise Green Belt from Lucky Peak Reservoir to South East Boise, which runs along the beautiful Boise River!

Our races host runners from all across Idaho and the Pacific Northwest, where runners have the ability to win great prizes provided by our local partners! Idaho Running provides custom medals and athletic apparel. We hope you join us for yet another year of competition, community, and most of all, a time to enjoy the great outdoors!
