Shanaze Reade using Beijing 'failure' to fuel 2012 Olympic fire
BMX world champion Shanaze Reade says that she is using her failed bid for gold in Beijing as a motivating tool for success at London 2012.
The British rider was favourite at the 2008 Olympics, before a crash in the final ruined her hopes of a medal.
Reade takes part in the BMX 2012 test event at the Olympic Park in Stratford on 19 and 20 August.
