Tiger Claw : May 8-9, 2026 (Issaquah, WA)

Tiger Claw is a trail event on Tiger Mountain with multiple race formats based at the Issaquah Community Center. The event emphasizes steep climbs and technical Pacific Northwest trails. The full 50k is described as about 31 miles with roughly 8,500 ft of elevation gain on rugged terrain. The Ascent is a vertical race up West Tiger 2 via the Cable Line route: 2.5 miles with about 2,500 ft of climb, followed by an untimed 3 mile descent back to the trailhead.

• Ascent - straight vertical ascent to West Tiger 2, timed at the summit.
• 50k / 31 miles - single-loop event with significant elevation.
