Ethos Endurance Festival

San Diego

Because two races are waaay better than one, this inaugural fitness fest for the moderately insane pairs a muddy, obstacle-filled, 8k SEAL Adventure Race, with two 400m swims broken up by a pair of 2mi runs. Survive it all and they'll reward you with up to six DVDs of GI Jane starring Demi Moore! a post-race music fest headlined by Ozomatli.
