Rocky Mountain Slam

Rocky Mountain Slam

The Rocky Mountain Slam is a series of 100 mile mountain races centered on the Rocky Mountain region with event operations based in Logan, UT. The series was created in the early 2000s to group several Mountain West 100 mile races. Registration is required to compete in the series and registration for this edition closes Wed, Jul 15 at 11:59 PM MT. The Bear 100 is the mandatory final race of the series.

Since 2022 the series has run as Rocky Mountain Slam V2.0. Under this format runners must complete at least four total races, with only The Bear 100 required. The series roster provides multiple race options to reduce the impact of lotteries and limited entry at some events. There is no formal overall time record; organizers will keep an informal summation of a runner's fastest four finishes including The Bear.

Recent changes and notes include the series not being held in 2020 due to COVID-19, the V2.0 relaunch in 2022, Scout Mountain 100 added in 2024, and High Lonesome 100 and Crazy Mountain 100 added in 2026.
