We can't promise you'll live to 100 if you run Marin County's annual 7-mile Dipsea cross-county race. But it worked for Jack Kirk.

The race is open to competitors of all ages, and we mean all: Kirk ran every race from 1930 to 2002, finally retiring at age 96; he died a centenarian.

Marin County, at the north end of the Golden Gate Bridge across from San Francisco, is known for its liberal politics and its natural beauty: it features both Muir Woods and the Point Reyes seashore. And get yourself indoors, too: Marin is home to the Mill Valley Film Festival and, in San Anselmo, a top destination for antique shopping.

NEXT: 8. Olmsted County, MN
