UCI BMX Supercross takes to the BMX track at the Olympic Park tomorrow, doubling as an Olympic test event.
If you were lucky enough to get spectator tickets you'll be amongst the first to watch sport on the Olympic Park and you'll be watching the riders race the track for the first time too.
Watch out for British rider, Shanaze Reade, who crashed out in Beijing in pursuit of medal glory. At 22 Reade is one of the most experienced competitors but she'll face tough challenges from New Zealand, Australian, French and Colombian riders.
Action begins on Friday with qualification rounds and finals on Saturday.
