Onward Shay! Boise Marathon is a 5K, 10K, half and full Boston-qualifying marathon (& a kid's race!) located in the heart of beautiful downtown Boise, Idaho. Join us on October 27th, 2019!

To honor our dear friend Shay Hirsch, all proceeds benefit the Multiple Myeloma Research Foundation in order to get researchers closer to finding a cure for cancer. Also, a portion of the proceeds are donated to Shay's favorite local charities.

Register today for the fast, flat course which weaves through vibrant downtown Boise, the beautiful greenbelt, and Boise's scenic neighborhoods.
