About
The Jasper Mountain Trail Fest in Dayton, Washington, on June 19, 2027, raises funds for the Jasper Mountain Reserve, a conservation organization working to improve wildlife habitat in Washington State's Blue Mountains. The program includes the Jasper Mountain Trail Relay (62 miles / 100 km), the Trail Marathon (26.2 miles / 42.2 km) and the Trail Half Marathon (13.1 miles / 21.1 km), all starting at 7 a.m., plus the Trail Family Run (4.3 miles / 6.9 km) at 7:15 a.m.
Runners will be on singletrack trails, with camping and lodging options nearby. The event aims to raise public awareness of nature conservation while offering endurance enthusiasts a challenging and scenic setting. Participants should be ready for rugged terrain and bring what they need, as the reserve is remote.
