Run Pick of the Month - Slacker Half Marathon

 Over 2,000 feet of descent at this downhill half marathon happening June 22, 2024.

Slacker Half Marthon runners follow an exhilarating point to point course from the base of Loveland Ski Area (10,630 ft) to the post-race party in historic Georgetown (8,400 ft).

Participants will receive a Long Sleeve Tech Shirt, a Finisher Medal, and the joy of indulging in one free beer (non-alcoholic option available).

One addition that we really like is that they offer free downloadable race photos.
