The Yellowstone Rim Runners is THE running club for Billings, Montana and all of Yellowstone County. Our mission is to provide a structured organization, within our community, for the purpose of promoting running as a sport and healthy lifestyle choice. We are the Road Runners Club of America affiliated running club for Billings, Montana. We have weekly club runs, four races, and are involved in our community in a number of ways. We have changed the club membership process and ask folks to join the club via this club page. 2020 is the last year we will utilize the Shamrock Run as membership entry. We anticipate offering discounts to club members on the Shamrock Run, and club members will also have opportunities for member only activities. We welcome all runners and walkers to our club runs, but ask that if you plan to attend regularly, please join the club.
