Mac's Run

Bear spray is required at Mac's Run, indicating the nature of the day. The Meeteetse Absaroka Challenge, or MAC, is a high-altitude mountain trail race in Wyoming’s Absaroka country. It offers a 15K for a hard effort and a 5K that uses trails and is suitable for families and newer runners. The course features mountain views, rough trail sections, and weather that can change, prompting advice to dress in layers. The 15K has two aid stations and requires runners to carry at least a water bottle. The 5K is open to a wider audience. The event began over 20 years ago and concludes with a post-race party. Registered runners receive burgers, food, and drinks, with options for friends and family to purchase.
