An expert guide to the London 2012 Olympic BMX track

Britain's Shanaze Reade and Liam Phillips guide you through the London 2012 Olympic BMX track.

The track was designed and approved by the sport's international federation the UCI, with the aim of "pushing the boundaries" of the sport.

It features an eight-metre-high ramp at the start, followed by a series of jumps, bumps, tightly banked corners, an innovative underpass in the women's races and a platform jump for the men's event.
