Comfortable temps, big temp swing

Mild 56°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 82°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

The Missoula Half Marathon is a flat, fast point-to-point course on the Sunday of race weekend. It starts in the countryside, follows a stretch of the Clark Fork River and finishes in downtown Missoula just past the Beartracks Bridge, in front of the Wilma Theater. The route is USATF-certified and sanctioned. It joins the marathon course a few miles in, and cones separate half and full marathon runners over the final miles.
