Mountain Trail Running Has Never Been Better

One of Oregon’s favorite trail full marathon and half marathon races returns for the 21st year on Saturday, August 9th, 2025. 

No pavement here. Featuring a full all-trail marathon, a half marathon, and a 6.5-mile course (dubbed the “Half As”), the Haulin’ Aspen features beautiful trails that wind through the Deschutes National Forest, showcasing some epic views. With varying terrain and elevation, the cool wooded pine setting provides a challenging and exciting experience. Enjoy the beautiful single track, steep trails, fast descents, and amazing views starting at an elevation of nearly 5500'. Make it a destination this summer – Bend and the Cascades welcome you!

This year, our event has been selected as the USATF Oregon Mountain Trail Marathon and Half Marathon Championships. If you wish to compete in one of these championships, you must be a USATF member and check the USATF Oregon Championship box when you register for the Marathon or Half Marathon.
