The Rocky Mountain Slam Series
The Rocky Mountain Slam (RMS) is a long-distance running series focused on 100-mile races located within the Mountain West region. Originally established in the early 2000s, the series has evolved to accommodate the increasing difficulty of gaining entry into specific events through lotteries. The current format, known as V2.0, requires participants to complete a total of four qualifying races within a single season.
The series concludes in Logan, Utah, where the final mandatory event takes place. To successfully complete the series, runners must finish The Bear 100 and any three other events from a designated list of mountain races. These races are spread across the summer months from June to September.
Participating Races
Runners can select their optional races from the following events:
- Scout Mountain 100
- Bighorn 100
- Hardrock 100
- Leadville 100
- Wasatch Front 100
- Ouray 100
- Wyoming Range 100
- High Lonesome 100
- Crazy Mountain 100
The Bear 100 is the only mandatory finish required for all participants in the series.
Registration and Ranking
Participants must register for the series specifically to cover administrative costs and the provision of a finisher award. While there is no formal overall time record maintained due to the differing nature of the courses, an informal summation of a runner's four fastest times, including the mandatory final race, is tracked. Registration for the series should be completed after a runner has secured entry into their chosen individual races. Visit the organization's website for the most recent information.
