The Rocky Mountain Slam is presented as a multi-race ultra series with an event date in Logan, UT on September 25, 2026. The series requires runners to complete at least four races, with the Bear 100 designated as the mandatory final race of the series. The event page lists an entry fee of 99.40 USD and notes that registration for this Rocky Mountain Slam entry opened on January 1, 2026 and that registration for the event closes on July 15 at 11:59 PM Mountain Time.
The current Rocky Mountain Slam is described as V2.0, a revision intended to broaden access after previous difficulty gaining entry to some legacy races. The series structure allows runners to select from a group of Rocky Mountain one hundred mile races while keeping the Bear 100 as the required finish.

The series history notes that Bighorn was added in 2003, Ouray substituted for Hardrock in 2019, the series was not held in 2020 due to COVID 19, V2.0 was announced in 2022, Scout Mountain 100 was added in 2024, and High Lonesome 100 and Crazy Mountain 100 were added in 2026.
