Beaverhead Marathon
Beaverhead Marathon race day weather
Cool start, warming trend ahead
Runners will face a temperature climb from 46°F at the start to a warm 72°F by the finish. Winds will be a significant factor, with headwinds impacting early miles and crosswinds throughout, especially in miles 1-3 and 5-9. A tailwind will finally assist runners in miles 11-12 and 19-27, providing a welcome boost. Hydration will be crucial as temperatures rise; starting conservatively will help manage the heat later in the race.

About the Beaverhead Marathon
The Beaverhead Marathon is an annual marathon and half marathon in Dillon, Montana, organized by the Montana Events Foundation (also branded Montana Running Company). Both races start and finish at Beaverhead Brewing Company in downtown Dillon. The marathon course is about one-third dirt and two-thirds pavement; the half marathon is entirely on pavement. The route passes through agricultural land with views of the Pioneer, Blacktail, Sweetwater, Highland, and Tobacco Root mountain ranges, at an elevation around 5,240 feet. First run in 2018, the race was cancelled in 2020 due to COVID-19 and has run every year since.
