During the 2006 Urban Assault Race in Los Angeles,  participants ride "Big Wheels" around a race track that was staged in the parking lot of Gold's Gym in Venice. Participants rode  through Santa Monica, Venice, and Marina Del Rey as they completed many fun challenges along the way. The Urban Assault Race™ is a combination of an adventure race, scavenger hunt and bike race. Teams of 2 raced through the city to reach checkpoints where they performed fun physical and mental challenges. The  race distance  was approximately 20 miles and included many checkpoints along the way plus a  final challenge at the finish line.
