Boise Half Marathon

Boise Half Marathon is run in Boise, Idaho, on November 14, 2026, with a 9 a.m. start over the half marathon (13.1 miles). The route uses the Boise Greenbelt path network, and every finisher takes home a shirt and a medal. Runners of all levels are welcome, and the event leans on its community feel.

Path running has its own character: the surface is consistent and largely free of traffic, but conditions along the river can vary and occasional construction may affect the route, so check the details in race week. Wildlife along the Greenbelt is part of the experience. A 9 a.m. start is late enough that you can eat properly and warm up without hurrying. For a first half marathon, count on roughly 12 weeks with a long run each week; for a faster time, add one session a week at your intended race pace.
