Washington · Snoqualmie Pass (Hyak)

Yeti Washington

Launched in 2020, the Yeti Washington runs 98.9 miles out-and-back on the Palouse to Cascades Trail — crushed limestone with grades never exceeding 5% — from Hyak through the 2.3-mile Snoqualmie Tunnel and east toward Easton before returning. The tunnel, dark and 34°F year-round, must be crossed twice and requires a light. With only 1,916 feet of total gain, the course prioritizes volume over vertical; the 30-hour cutoff and 85% finish rate reflect its accessibility relative to most mountain 100s.
