Glacier National Park Half Marathon

Glacier National Park Half Marathon takes place on June 26, 2027, in Browning, Montana, just outside Glacier National Park. The race covers 21 km (13 mi) on a technical mountain course among peaks and lakes. Start times and elevation gain are not listed in our records.

Technical mountain ground turns a half marathon into a two-and-a-half to three-hour effort for many runners rather than a two-hour one: plan your nutrition as you would for a long trail run, not for a road race. Late June at this latitude can still deliver snow on the higher sections, so check the conditions the week before and carry a light layer rather than assuming summer.
