Soaring Eagle Trail Run

Soaring Eagle Trail Run : May 16, 2026

Soaring Eagle is held at Soaring Eagle Regional Park in Sammamish, Washington (26015 E Main Dr). The event offers the following distances:

• 5K
• 10K
• Half marathon

The event is presented by Arc’teryx Seattle.

Course and logistics

All distances begin on the Pipeline Trail, which crosses the park and is wide and well maintained. At about 0.74 miles the 5K and 10K routes diverge: the 5K takes an abbreviated loop back to the finish, the 10K follows a longer loop through winding forest singletrack, and half-marathoners complete the 10K loop twice. Trails are mostly flat and well graded but include roots, rocks, and puddles to watch for. Published elevation gain is: 5K 200′, 10K 700′, Half 1400′.

Aid stations provide Tailwind electrolyte drinks plus fresh fruit, gels, gummies, and other treats. Aid locations include 4.5 miles on the 10K route and 4.5, 6.5, and 11 miles for the half. Trails remain open to other users during the event, including equestrians, cyclists, and pedestrians.

Additional notes: the event is cupless, so runners must carry a refillable container; parking is available at the park and on E. Main Dr (park only on the south side of Main Dr); online registration closes the Friday before the race. A free Woodland Speeders kids race runs a 0.5 mile very flat course; every finisher receives a piece of handmade finisher swag. The event supports the Washington Trails Association and includes non-binary registration and awards options. Visit the organization's website for the most recent information.
