Gaspin Through The Aspens
Welcome back to Gaspin’ Through the Aspens! We’re thrilled to return for our second year, and even more excited to announce the addition of a brand-new 50-miler to the lineup. This race showcases some of the most breathtaking trails in American Fork Canyon, weaving through dense Aspen groves, rugged climbs, flowing descents, and panoramic mountain views that make every mile unforgettable.
Whether you’re here to tackle the new ultra distance or to return for the classic courses you already love, this year promises an even better experience — bigger challenges, stunning scenery, and the same supportive High Altitude Races community.

Experience the Adventure
Designed by runners for runners
This course was thoughtfully designed by the race directors with one goal in mind: to create a route they themselves would want to run again and again. Every climb, descent, and stretch of singletrack was chosen to showcase the best of the Canyon—challenging enough to be memorable, yet so beautiful and rewarding that you'll want to return year after year.
