Mt. Si Relay & Trail Runs
The Mt. Si Trail Races began as the “Falls to Gasworks Relay” in 1983, beginning at Mt. Si High School near Snoqualmie Falls and ending at Gasworks Park in Seattle.
Today, the half marathon, marathon, 50K, 50M and relay are run on the scenic Snoqualmie Valley Trail with the marathon, 50K and 50M continuing to run east on the Palouse to Cascades Trail. The trail is old railroad grade with a gentle climb from North Bend to Rattlesnake Lake.
