Billings Skyline Races

Half marathon & 30K

Great Views. Challenging Course. Unforgettable Experience. The Skyline Races Half Marathon and 30K brings runners to the top of Billings’ legendary Rimrocks for a race like no other. Experience Montana’s wide-open beauty on a paved path of moderate elevation changes that makes it ideal for both competitive athletes and first-time half-marathoners or 30K participants. Featuring breathtaking views of the Yellowstone Valley and the Beartooth Mountains, the Skyline Trail section travels along a sandstone ridge, offering sweeping panoramic views. Runners then connect to Skyway Drive, a newer path with gentle curves, rolling hills, open terrain, and distant mountain backdrops. Both distances loop into the Alkali Creek Trail, following a shaded stretch along the creek before heading back toward the finish line at Two Moon Park.
