The picturesque setting of Alpine County is the location for the exciting 25th Annual Bear Valley Triathlon. The popular Central Sierra Labor Day Weekend tradition will be held on Sunday morning, Sept. 3, the day before Labor Day Monday, at Bear Lake, in Bear Valley Village. Nestled in a mountain location, the triathlon course features a 600-yard swim (warm water, close to 70 degrees, wet suits are allowed, but not necessary); 10.5-mile bike ride (rolling, climbing loop course); and 3.4-mile run (rolling road).
