Early humans developed the ability to sprint in order to chase down sprightly prey and invented long-distance running to escape from slowly approaching glaciers. Follow in their fossilized footsteps with this Groupon.
$25 for Individual Registration ($50 Value)
On Saturday, October 6, racers take off at one of five start times—from 8 a.m. to noon—to run, jump, and wade through a 3.1-mile obstacle course. All registrants also receive a shirt and free admission to the Mud Fest afterparty. With this deal, register either as an individual or as one member of an unlimited team of muck monsters or fellow humans.
For 2012, proceeds from the event benefit the Challenged Athletes Foundation's Operation Rebound, which helps rehabilitate injured soldiers, veterans, and first responders with the healing power of sport.
Del Mar Mud Run
For the fourth year in a row, the San Diego County Fair 5K is setting up shop at the historic Del Mar Fairgrounds. A sell-out event in each of its first four runs, the event has gained notoriety for its national TV spots and attendance by reality-TV stars. This year's race will keep everyone on their muddy toes, though, as a brand-new course will introduce different obstacles and a possible redefinition of true north. Participants can sign up as individuals or a team; either way, they can hit up a post-race foam fest with hot showers and a dance party.
