Bozeman Half Marathon & 10K

The Bozeman Half Marathon & 10K takes place in Bozeman, Montana, on September 12, 2027. The half marathon (13.1 miles / 21.1 km) starts at 8:00 a.m., followed by the 10K (6.2 miles) at 8:15 a.m. Both courses run through the Gallatin Valley, framed by Montana's mountain ranges: they start in the southern foothills and descend to the finish on Main Street.

The mostly downhill profile lends itself to chasing a fast time, provided you don't go out too hard: the early downhill miles load the quads, and runners coming from sea level need a few days to adjust to the valley's elevation. The 10K suits those who want a solid effort without committing to the full half. Close to Yellowstone National Park, the area lends itself to a longer stay after the race.
