Jasper Mountain Trail Fest 2026
The Jasper Mountain Trail Fest takes place at the Jasper Mountain Reserve in the Blue Mountains of southeast Washington. This event serves as a fundraiser for an environmental non-profit organization dedicated to enhancing wildlife habitats for native flora and fauna. The races are held on three specific single-track rail loops: the 3.3-mile Red Loop, the 4.4-mile Green Loop, and the 5.4-mile Black Loop.
Participants can choose from several trail running distances:
- 4.3-mile Family Run: A course on the Green Trail with minimal elevation gain.
- 13.1-mile Half Marathon: A solo race with 2,570 feet of elevation gain.
- 26.2-mile Full Marathon: Two laps of the combined loops with 5,140 feet of elevation gain.
- 52.4-mile Relay: A 4-person team event where members rotate roles to complete the loops.
The 4-person relay requires each member to complete all three loops. Team members exchange a bib belt after each individual loop is finished. For individual runners in the half and full marathon distances, the course covers the combined trail loops.
The event site is off-the-grid, meaning there is no electricity or running water available. On-site camping is provided at the reserve for participants, and parking is included in the registration fee. The reserve is a quiet zone where car engines, generators, and loud music are prohibited. Portable sanitary facilities are provided, and participants are required to carry out all trash.
The start and finish line is located at 934 Payne Hollow Road in Dayton, Washington. Nearby accommodations are also available in local towns such as Dayton, Waitsburg, and Walla Walla. Visit the organization's website for the most recent information.
