Running Up for Air | Mt Sentinel
Running Up for Air Mt Sentinel is a winter endurance event held on Mt Sentinel, with activities based at Phyllis Washington Park in Missoula, MT. The event turns laps up the mountain into fundraising for local air quality and climate work. Mt Sentinel is listed at 5,158 feet elevation.
The event offers multiple timed options:

Participants attempt to summit the mountain as many times as possible during their chosen time window. With each registration a fundraising page is created and participants are encouraged to collect pledges from supporters for each completed lap. All proceeds from the event go to Climate Smart Missoula to support local efforts on air quality and climate solutions.
Climate Smart Missoula is described as a Missoula based nonprofit with over ten years of local climate work. Examples of their activities include helping keep indoor air clean during wildfire smoke, planting trees, transitioning methane gas powered systems to more efficient electric systems, and supporting solar projects.
