The Grizzly 100/75 has become an international attraction for mountain bikers from all over the world. With some of the most challenging single-track, double-track, and fire road climbs and descents, participants love to challenge themselves and others on this high altitude course (at 7000-8500 feet elevation). The Clarks Grade Climb has made a name for itself as one of the most dreaded 5 mile climbs in Southern California. The Grizzly 100k NUE Century Challenge and the 70-75k NUE Marathon Challenge welcome racers and riders to Big Bear Lake, CA. The Big Bear MTB Gran Fondo with sport rides of 30/50k rounds out the day’s events. Astonishing aid stations, friendly volunteers, and lots of local enthusiasm for this event make it a great finish to the NUE Series.
