About this race
Join Missoula Adaptive Recreation and Sports (MARS) for the first-ever Marshall Mountain MARS-a-Thon inclusive mountain bike race and fundraiser to support adaptive sports programming in Missoula and the surrounding area. This campaign is all about FUN, celebration, and generating support for the MARS mission!
MARS' mission is to enhance the quality of life for people with disabilities through recreational activities & advocacy.
We are coming together to embrace summer in the mountains and celebrate our community that transforms lives in Missoula and the surrounding areas. We are also celebrating the Mission to MARS trail at Marshall Mountain winning Best Adaptive Trail of 2025! This trail was made possible through a collaborative effort between Marshall Mountain Park, Missoula Mountain Bike Coalition, and Missoula Adaptive Recreation and Sports along with support from many more local partners and dozens of volunteers.
