Each year, St. Luke's FitOne draws thousands of people of all ages to downtown Boise for its 5K, 10K and half marathon races. But it's more than a great way to spend a September morning—it's a platform to promote healthy living and make memories that racers can cherish for years to come.
The FitOne half marathon course is a picture-postcard tour of Boise. Racers pass by the Idaho State Capitol, Boise Depot, Old Idaho Penitentiary and Idaho Botanical Garden, among others. Racers are welcome to bring strollers on the course—we just ask that you start the race toward the back of the corral, behind the competitive runners. No scooters or bikes are allowed for safety reasons.
Gear check will be available on race day—look for the Norco van in front of the capitol building and at the Finish Festival.
Please note, this course is not certified by USATF and will open to traffic at 11 a.m. Only service animals are allowed. Race day is Saturday, September 20, 2025.
