Coverage from Manchester of the World Championship trials, introduced by Hazel Irvine. A maximum of three places are on offer for each event, but a top-two finish will only earn selection provided those athletes have also regularly achieved the highest qualifying standard throughout 2007. Among the highlights should be the men's 400m final featuring fit-again former European number one Tim Benjamin, world junior medallist Martyn Rooney and current top-ranked Briton Andrew Steele.
Commonwealth triple jump champion Phillips Idowu is up against European silver medallist Nathan Douglas, while Marlon Devonish looks to reaffirm his resurgence over 200m. Natasha Danvers-Smith and Lee McConnell go head-to-head in the women's 400m hurdles, and leading distance runners Mo Farah and Jo Pavey are also in action.
