Obstacle courses are metaphors for life's trials—tall walls represent unaccomplished goals, narrow bridges represent the fear of failure, and mud pits represent the daily grind at the mud-pie factory. Conquer what holds you back this Groupon.

$29 for Mud Factor Obstacle-Course-Run Entry ($55 Value)

At Baja Acres on Saturday, June 30, competitors don event T-shirts and bandanas before tackling fun, challenging obstacles in waves that depart every half hour, with the first available wave starting at 9 a.m. and the last leaving at noon. Finishers receive a medal; runners 21 and older also enjoy a complimentary beer. Parking (not included in this Groupon) is $10 per car. View the course map here.
