The gateway to Mount Rainier National Park serves as the host for this popular season opening event. This event begins at the Enumclaw Expo Center. The long course goes 5.1 miles using the local roads. Once on your bike, you will ride on rural roads through farm lands (watch for Mount Rainier) riding up Mud Mountain Dam Hill and come to a screaming decent down Highway 410 taking a hard left to the Expo Center and you get to do this 14.4 mile loop one more time. The final run is again on local roads, actually taking you to the base of Mount Peak completing 3.8 miles.
