About
A rugged 100-mile ultramarathon through Washington's Central Cascade Range near Easton, following singletrack trails with steep climbs, alpine ridgelines and technical descents. It's one of the Pacific Northwest's classic mountain ultras, testing runners with sustained elevation gain and rocky terrain.
