Half Marathon races near Boise

Boise Training Notes

Boise hosts 4 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals use the Greenbelt for flat Z2, steady base miles, and easy shakeouts along the Boise River. The Greenbelt is our city’s shining gem when your legs need uninterrupted pavement. Fort Boise adds gravel roads and trails when you want bite without driving far. Boise Run Club meets Tuesdays at 6:30 pm at Payette Brewing for casual 1-4 mile runs. Tree City Track Club hits Boise High School on Wednesdays at 5:30 am and Payette Brewing on Sundays at 7:30 am. Bogus 50/50, Boise Marathon, St. Luke’s FitOne, and Boise Trails Challenge anchor the calendar.

Locals ride the Boise River Greenbelt when the plan says easy spin, coffee pace, or recovery after intervals. The Greenbelt runs 8 km and 21 m of elevation, so it stays friendly. The route to Table Rock is 9 km and climbs 135 m from Municipal Park. Great Rides Boise keeps the club side simple. Lost River Cycling runs a year-round Sunday road ride from Mountain Timber Coffee on North Bogus. Boise Foothills, Rocky Canyon Road, Table Rock, Bogus Basin Gravel Cycling, and Shane’s/3 Bears/5 Mile Gulch/Watchman’s Loop bring the climbs.

Spring and fall are the best months because Boise stays mild and the foothills feel close without feeling heavy. Summer brings hot, dry days, so locals ride and run early, then save Z2 for shade along the river. Boise Marathon lands on June 20, and the long light helps even when the day throws a few moods at you. Winter Warriors runs from late November to mid-February with 5-6 meetups per week. Wilson Creek and 8th street moto become useful when foothill conditions get touchy. The desert keeps riding possible when winter turns the regular singletrack into a chore.
