London athletes face tough Olympic trials

This evening is a crucial one for many London athletes who are targeting a place in the British team for the London Olympics. Athletes who come in the top two in their event at the UK Athletics Trials will book their place at Stratford as long as they have proved they can make the Olympic A qualifying standard. And tonight will be judgement night for many of the capital's leading runners.

The men's 100m competition is particularly fierce, with the semi-finals and final coming tonight. Dwain Chambers won his heat yesterday but is yet to make the A standard of 10.18 seconds this season. 18 year-old Adam Gemili also won his heat and posted a time of 10.08 earlier this month. Other London contenders include James Dasaolu, Harry Aikines-Aryeetey and Tyrone Edgar.

The Olympic selectors do have the discretionary power to pick a third sprinter to compete in the 100m, but anyone finishing outside the top two tonight will just have to cross their fingers.

The women's 100m final is also tonight with Abi Oyepitan and Jodie Williams in the running. And Olympic champion Christine Ohuruogu was the fastest qualifier yesterday for tonight's 400m final.

Not competing though is the former world triple jump champion Phillips Idowu who has pulled out of the trials with a minor injury problem. And Mo Farah has pulled out of tonight's 1500m final so he can concentrate on running a 5000m race in Helsinki next week.
