Frost Eagle Trail Run
Frost Eagle Trail Run takes place at Soaring Eagle Regional Park in Sammamish, WA, and is the sixth event in the 2026-27 Winter Trail Series. The event offers two distances:
- 5 mile
- Half Marathon
Courses feature rolling hills that are mostly short or moderate in grade. Much of the route is on technical singletrack that can be narrow, twisty, and filled with roots and rocks. A short section uses the Pipeline Trail, which is mostly groomed gravel but can become muddy. The half marathon follows the mapped loop twice.
Both courses form a figure 8. The primary aid station sits at the intersection of the 8 so runners pass it twice per lap; half marathoners pass it four times total and 5 mile runners pass it twice. A second aid station adjacent to the start and finish provides additional support for half marathoners. Aid stations provide water, Skratch Labs electrolyte drink, and a selection of carbohydrate or salty foods such as cookies, energy bar pieces, gels, chews, chips, bagel, fruity candy, fig bars, peanut butter and jelly sandwiches, and bananas.
The start and finish are at the park main entrance on the west side with a paved parking lot; no parking pass is required. Street parking is available on the south side of E Main Dr. The lot is small and many participants will need to park on the street and walk several hundred meters to the start.
Dogs are not allowed on the course. Trails remain open to other users during the event and participants are responsible for their own safety. Runners under 20 years old are eligible for a $10 discount on registration. Visit the organization's website for the most recent information.
