Cycling & running events in Boise, 2026

Boise Base Miles And Foothill Vert

Running: Locals run the Greenbelt when they want flat base miles and clean rhythm beside the Boise River. The Greenbelt gives runners more than 27 km of uninterrupted path, so Z2 days can stay simple. Fort Boise gives trailheads with gravel roads, and Military Reserve puts the Foothills XC12K right into the Boise Foothills. Boise Run Club meets Tuesdays at 6:30 pm at Payette Brewing for a casual 1-4 mile run. Boise Area Runners, Tree City Track Club, Trail Fridays, and Boise Long Run Club keep the week covered. City of Trees Marathon, Boise Front Trail Festival, Bogus Trail Series, and Dirty Dog Trail Marathon and Half Marathon anchor the calendar.

Cycling: The Greenbelt runs 8 km with 21 m elevation. The route from Municipal Park toward Lucky Peak State Park runs 9 km with 135 m elevation. Great Rides Boise, Lactic Acid Cycling, BYRDS Cycling, Crank Queens, Radical Adventure Riders - Boise, and SWIMBA make the scene feel busy without feeling closed. Bogus Basin, Table Rock, Rocky Canyon Road, and Shafer Butte hold the climbs. Around Arrowrock Loop goes 139 km with 2,341 m elevation gain. Over the Hill Gravel Grinder 2026 and the 2026 Bogus Basin Hill Climb give riders an anchor event.

Season: Spring and fall give Boise the best running and riding months, especially when the Foothills feel fast and the Greenbelt stays easy. Summer brings hot, dry days, so locals start early, keep intervals short, and save long Z2 for the Boise River or shaded park links. Bogus Trail Series turns Friday evenings into trail-race time near Simplot Lodge, and bigger rides toward Lucky Peak or Swan Falls need honest bottles. Winter changes the rhythm instead of ending it. Winter Warriors meets 5-6 times per week from late November to mid-February, and BYRDS weekly training rides run from February through October. Moderately cold winters push more runners to roads and more cyclists toward gravel, cyclocross habits, and steady no-drop rides.
