Pleasant conditions, gradual warm-up

Runners will face a pleasant start at 56°F, with a gradual warm-up to 67°F by the finish. The wind will be light at 6 mph, with moments of crosswind and headwind, particularly between miles 10-12. Runners should maintain a steady pace, particularly during the headwind segments, and hydrate well as temperatures rise. Conditions will remain dry, making for an enjoyable race experience.

The finish is 15 miles from the start, so we look at it at 2 points, not just the start line. In a typical year, at 9:00/mi, you start at 56° and finish around 9:55 AM in 67°; typical start-line conditions say 70° then.

Race Info

The Missoula Marathon is the brainchild of a group of local, dedicated members of Run Wild Missoula who want to share the area’s beauty and Missoula’s unique feel with runners from all over. The Missoula Marathon is one of our community’s most beloved and supported events. The Missoula Marathon has been named as the Best Marathon In The U.S. on several occasions – in 2010 by the readers of Runner’s World Magazine and in 2017 and 2018 by The BibRave 100. Runner’s World has also named the Missoula Marathon as a Top Marathon For Back-Of-The-Packers (2017) and a Top 10 Bucket List Marathon (2018, 2019 & 2020). Source
