With the Fall Season, Estes Park shines in colors and wilderness experiences! Herds of Elk begin to roam the meadows and open fields; while sounds of bugling Bull Elk call out their territory. Join us as we acknowledge this unique season at the RUT RUN 5K as part of ‘ELK FEST’. Kick starting the weekend of events, the 5K (3.1 miles) race offers a short and scenic tour of fall colors, river views, and possible Elk encounters (from a safe distance).

Our fabulously scenic, downhill course that starts from Fish Hatchery Road on the Fall River Trail and finishes at downtown’s Performance Park continues!

Runners, joggers, walkers, and strollers will be transported from the Estes Park Visitor Center by the “Hiker Shuttle” to the Start area on Fish Hatchery Road. Following the winding and scenic path, you will enjoy the radiant golden Aspen colors, hear Fall River and pass by the historic Elkhorn Lodge. This run will quickly ignite your senses and appreciation for nature and its splendor. After the run, participants can purchase various delicious foods from nearby restaurant BIG HORN CAFE, several restaurants along Elkhorn Ave or Food Trucks at Elk Fest in Bond Park. All runners receive a complimentary beer token for the Elk Fest festivities!
