Athletics starter Alan Bell fired the starter gun for this summer’s 100-metre race that featured Usain Bolt, Yohan Blake and Justin Gatlin. But as Alan – the Youth Sport Trust’s international development co-ordinator – reveals here, he already knows Olympic champion Bolt well.

Here, Alan discusses disqualifying the Jamaican runner at the 2011 World Athletics championships in South Korea and seeing Bolt setting a 100 metres world record of 9.58 seconds at the 2009 World Athletics championships in Berlin.
