22:47 GMT, 1 April 2012
The Olympic Stadium was handed over to charities on Sunday with hundreds of runners given the chance to race on the track Usain Bolt, Jessica Ennis and Co will go for gold on this summer.
The Gold Challenge gave dozens of charities the chance to use the facilities at the venue in Stratford, east London for the day, with celebrities such as Katie Price, Steve Backley and Austin Healy invited along to promote good causes.

And they're off! Kay (centre) races down the track
Among the competitors, running for the children's charity the Rainbow Trust, was Sportsmail's Alex Kay. But his 100 metres race did not end in glory as he finished third in 14.05secs in a race in which Healy finished second.
Kay was a little rusty out the blocks but recovered well, only to miss out on the Olympic qualifying time. No place in Team GB then…

This weekend was the first time the stadium has been used, with competitors put through exercises in the warm-up area under the stadium before their races and photographed on the podium after the finish. All competitors were given medals to mark the day.
