Welcome! Onward Shay! Boise Marathon takes place October 28th, 2018, at 9AM. The Onward Shay! Boise Marathon is a 5K, 10K, half and full marathon, including a kid’s race as well as relays (and the option to run with some of the biggest legends in the history of running!) We will begin and end in beautiful downtown Boise. The race is certified as a Boston Marathon qualifier. The course follows the greenbelt, a paved path that spans miles of connected parks alongside the beautiful Boise River from one end of the city to the other. Racers will pass by Boise State University before weaving in and out of downtown Boise, past the state’s Capitol Building and then travels through scenic Boise neighborhoods, including Harrison Blvd., Warm Springs Blvd., up 13th St. and through Hyde Park.
