"Standard distance. Mammoth vert."
Mammoth Bar Trail Runs take place on the single-track and double-track trails of Mammoth Bar OHV Area in Auburn State Recreation Area, in the Endurance Capital of Auburn, California.
Mammoth Bar is known for its steep climbs and descents, as well as it's beautiful American River Canyon views.
These are not your average courses. You get more vert per dollar! Yay!
