At the dirt laboratory, 85 flow-rats master the maze, a 20-second course chock full of berms, doubles and gaps. The ultimate stripped-down skill showcase, riders duel back-to-back without making a single pedal stroke, in a test to harness horizontal momentum with pumps and doubles, manuals and air.

The first 60 pro men and 25 pro women to register will hustle through a time trials elimination round to form the finals field of 32 men and 8 women. $1000 cash will crown the fastest female and male rider.

Will reigning title-holders Mitch Ropelato (US) and Jill Kintner (US) rock-and-roll their way to four in a row, or is 2013 their time to be outpumped?
