Rocky Mountain Slam

The Rocky Mountain Slam (RMS) is a challenging series of ultra-distance races in the Mountain West, originally conceived in the early 2000s. The series includes iconic races such as the Bear 100, Bighorn 100, Leadville 100, and Wasatch Front 100, with the Bear 100 being mandatory for completion. In response to the increasing difficulty of entering some races, the RMS has evolved to allow participants to choose from a broader selection of races while still requiring four total races to be completed.

The series aims to provide an exciting and memorable experience for runners, celebrating the unique challenges of racing in the Rockies. Visit the organization's website for the most recent information.
