San Francisco is lucky to be one of the rare urban areas with lots of hiking trails within our city limits. It's also one of the fittest cities in the country, ranking No. 5 in an annual list of health and community fitness. Instead of watching your progress up a blinking digital staircase, try hitting the road dirt on one of SF's many trails. We've even drawn up a map with courses to make things easy for you (just click the course photos to enlarge them). The shortest trail we've mapped is 1.7 miles and the longest is 10, so don't limit yourself by length, or even shoes—there's a barefoot jog right this way.
