Finally! A century ride with just the right amount of everything! Enjoy incredible views of some of nature’s finest scenery as you ride this fabulous route.
The ride begins with a beautiful cruise along pristine Siskiyou Lake, then test your mettle with a 
challenging climb up a scenic one lane windy mountain pass to Mumbo Summit along the Sacramento River. The river should be rushing and wildflowers blooming along the way! Enjoy a refreshing rest stop at the top of Mumbo Summit with fabulous views to the West. Then enjoy a fantastic downhill segment with distant views of Shasta lake, the Trinity Alps and Scott Valley.
