Lake Sonoma 8 Hr

Sept 16th. 2017 - 7.2 mile loop 90% single track, 1,100 ft per lap

Bringing it back, Hopper style! We’ve always loved the flowing and technical trails of the Liberty Glen area at Lake Sonoma so what  could be better than an all day mtb ride with your pals?  This killer loop is “practically” all downhill.


“Rest Stops”

We’ll have Hammer Nutrition Heed hydration and gels at the transition zone all day and mechanical support provided by BreakAway Bikes. Ice-cold Guayaki. Lunch and beer from Woodfour Brewing Company at the finish.
