Course Highlights
Haulin Aspen Trail Marathon & Half Marathon runs through the spectacular trail network surrounding Sunriver Resort and the Deschutes National Forest in Central Oregon. The course winds through golden aspen groves (at their most spectacular in late summer), old-growth ponderosa pine forests, and open meadows with sweeping views of the Three Sisters, Mount Bachelor, and Broken Top. The marathon and half marathon share the same scenic forest terrain, making this one of Central Oregon’s premier late-summer trail experiences.
Race Details
The 22nd Annual Haulin Aspen takes place Saturday, August 8, 2026, based near Sunriver, Oregon. Registration is through RunSignup. The course is a well-marked, well-supported trail race with aid stations staffed by enthusiastic volunteers. The modest field size (500-1,000 participants) gives the race an intimate feel that larger events can’t match. Sunriver Resort area provides excellent post-race accommodation and dining.
Why Runners Love It
Haulin Aspen is a beloved fixture in the Central Oregon racing calendar precisely because it combines challenging, beautiful trails with a welcoming community atmosphere. The aspen groves in August light are genuinely stunning — photographers as well as runners make the trip. At 4,200 feet elevation, temperatures are cooler than Portland or Eugene in August, making for ideal trail running conditions. The Sunriver area’s resort amenities make it easy to reward yourself generously after the race.
Race-Weekend Tips
Trail shoes with good traction are essential for the forest floor and aspen grove terrain. At 4,200 feet, sea-level runners should pace conservatively. Book Sunriver Resort or nearby Bend accommodation early — August weekends in Central Oregon are popular. The race fills to capacity; register as soon as registration opens.
