Sure, you can choose to follow the herd and run with 60,000 others, some of whom even will be clothed, in this weekend's Bay to Breakers in San Francisco.
But, if you don't like crowds, but still want to do something on the wild side, may I suggest heading to Folsom on Saturday for the Run With Nature? Sure, there's a 5K and 10K with hills (!!!), but that's not the wild part.
No, this year, race organizers are adding an event called "The Wild Way." It's a two-mile obstacle course inspired, perhaps, by the alterna-runners who practice the sport of parkour. It's not quite the same, but fun nonetheless.
Here's how the race organizers describe it:
The course takes you on a 2+ mile crazy rollercoaster of a run, over grass, gravel, pavement, and dirt; up hills and down hills; over fences, under barricades; through fields, along chutes; through the Zoo, up flights of stairs; and over logs spanning a mud moat. You won't get that dirty ... unless you happen to misjudge your step on the logs!
The best part is, they are holding the "The Wild" after the conclusion of the 5K and 10K. So you, theoretically, can do both the traditional and nontraditional runs.
