If you’ve been looking for a trail half marathon that feels less like a race and more like a trail celebration with a purpose, the Herron Half Marathon on Saturday, June 20, 2026, in Kalispell, Montana, might be exactly what you’re after. With rolling terrain, a loop course, and a mission that goes beyond the finish line, this 14th annual event is a standout for runners who love the outdoors and want to give back.
The Course: Rolling Trails Through Montana’s Beauty
Herron is a trail half marathon, so expect soft surfaces, gentle climbs, and descents that keep things interesting without overwhelming you. The rolling difficulty means there’s no massive mountain to conquer, but you’ll still earn every mile. It’s a loop course, which is great for logistics—you start and finish in the same place, making parking and spectating simple. The scenery is classic Montana: pine forests, open meadows, and views that remind you why you trail run. For first-timers, this is a welcoming introduction to trail racing. For veterans, it’s a chance to focus on effort and enjoy the ride.
The Experience: Small-Town Charm with a Big Mission
This race is organized by the Flathead Trail Builders (FTBT), and all proceeds go directly to building and maintaining over 40 miles of trails in the area. That means every registration fee literally paves the way for future runs. The atmosphere is community-driven—runners, volunteers, and sponsors all come together to support a shared love of trails. Expect a brief pre-race meeting 10 minutes before each start (7:00 AM for the half, 7:15 for the 10k, and 7:30 for the 5k), and note that parking is limited, so carpooling is strongly encouraged. It’s the kind of race where you’ll meet friendly people who are genuinely happy you’re there.
Who This Race Is For
First-timers: If your first half marathon is on trail, Herron is a solid choice. The rolling hills are manageable, the loop means you’re never lost, and the supportive vibe takes the pressure off. Plus, you’ll be part of something bigger—helping build the trails you run on.
PR-seekers: Trail half marathons aren’t typically PR courses, but Herron’s rolling terrain is runnable. If you’re aiming for a strong effort on dirt, this is a good bet. The loop course allows for pacing strategy, and the cooler morning temps (low around 46°F) help.
50-state chasers: Montana is a must, and Herron offers a true Montana experience—trails, community, and a race that’s been going strong for 14 years. It’s also part of the Flathead Race Series, so you can earn series points if you’re feeling ambitious.
