Is the month of August set in stone? Most of the SoCal, Central Cal, and NorCal runs will be in late June, or early July (when it hasn't gotten too hot). I'm sure you could easily combine with one of those groups, and have a blast! Either way, make sure your plans don't conflict with the Jeepers Jamboree, or you will have to pay big bucks to get on the trail during that time.
