Run Rabbit Run

Run Rabbit Run, in Steamboat Springs, Colorado, offers two ultramarathons—the 50‑mile and 100‑mile—welcoming both “Tortoises” and “Hares.” Runners traverse the scenic Routt National Forest amid autumn colors, with the 100‑mile route looping from the base to Mount Werner, across the Continental Divide toward Rabbit Ears Mountain, and back, while the 50‑mile course starts at the Steamboat Ski Area and climbs toward the high country. Elevation gain is about 9,000 feet for the 50‑mile and roughly 22,000 feet for the 100‑mile. The event champions endurance and camaraderie, featuring substantial prize money and a Team Challenge.
