Conquer the infamous Tiger Claw 50K on May 9, 2026, in Issaquah, WA, an experience designed to test even the most seasoned trail runners. This challenging ultra packs approximately 8,800 feet of elevation gain into rugged Pacific Northwest terrain, featuring relentless steep uphills and technical, quad-burning descents under a lush canopy of fir and moss. Runners begin with a mellow 4.6-mile warm-up on the "Green" loop to the Lower Aid Station before embarking on the race's most unique aspect: the "Choose Your Own Adventure" format. You'll tackle three distinct climbing loops—Yellow, White, and Pink—in an order you decide, each varying in length and difficulty, with a common descent back to the central aid station.

The course, praised for its gorgeous scenery and well-marked trails, is a true "early-year ass-kicking" that promises a physically and mentally demanding journey. Aid stations, located near the High Point Way parking lot and at the West Tiger 2 summit, offer typical trail running fare, water, and coke, though runners are encouraged to be self-sufficient, and trekking poles are not permitted. With typical race day conditions hovering around highs of 66F and lows of 48F and minimal chance of precipitation, the weather should be ideal for a day on the mountain. The atmosphere is consistently lauded as hard but fun, with a supportive community and dedicated volunteers making for a memorable event that culminates at the Issaquah Community Center finish line.
