  • Imogene Pass Run

    Starts in Ouary, CO. | Finishes in Telluride, CO. | Sept 8, 2018

    17.1 Miles | 5,000′ gain | 4,000′ loss

    The first known run over Imogene Pass, 13,114′, was that done by Rick Trujillo on Tuesday, August 6, 1974, when he ran from Ouray via the pass to Telluride (2:32:57), as a training run for the Pikes Peak Marathon, after a day’s work at the Camp Bird mine. A chance encounter with some Telluride people resulted in a formal race being established. On September 29, 1974, six runners participated in the first “Imogene Pass Mountain Marathon”. Rick was the first to cross the finish line, in 2:21:18.  Today the Imogene Pass Run has increased greatly in size and importance from its humble origins in 1974. Where once it was an adventure run for a few pioneers, today the race is immensely popular and the number of registered participants is by necessity restricted, due to safety and logistics reasons. From the original field of six, it has grown to encompass more than 1200 participants! website and registration
