Chambers comes out on top over young guns

Dwain Chambers proved he still is Britain's top sprinter by winning the 100m at the UK Athletics trials in Birmingham. The Belgrave Harrier ran a season's best time of 10.25 seconds to win, just ahead of 18 year-old Adam Gemili. However, Chambers' place in the British Olympic team is not yet guaranteed as he is yet to run the A standard qualifying time of 10.18. He is hoping to achieve that mark at the European Championships in Helsinki which start on Wednesday.

If Chambers is included in the British team, it will be a remarkable turnaround - he thought he would never be allowed to compete at an Olympics again after failing a drugs test in 2003. But a ruling by the Court of Arbitration for Sport earlier this year overturned the British Olympic Association's ban and gave Chambers his chance.

One London sprinter who definitely has qualified for the Olympic team is Gemili. The teenager came second in yesterday's final but has already achieved the A standard qualifying time when he ran 10.08 earlier this month. However, he is also planning to compete at the World Junior Athletics Championships in Barcelona in July which may mean he cannot compete at Stratford.

Also through to the British team is 400m Olympic champion Christine Ohuruogu. She was celebrating becoming an aunt yesterday and then won the 400m final in 51.89. She said she has approached the trials as preparation for the Games.
