Call of the wild: Jack London park challenges hardy hikers to conquer its 31 miles of trails

Bay Area folks who are dying to answer the call of the wild, go where the wild things are or while away a little time now have the opportunity of a lifetime — the Wild Trail Challenge at Jack London State Historic Park in the unincorporated community of Glen Ellen in Sonoma County.

For those who are tough enough to try it, the challenge is a series of five hikes on five consecutive Saturdays increasing in duration and/or difficulty each week, covering every trail in the park for a total of 31.2 miles, park officials announced this month.
