David Weir goes for one mile world record

London's own wheelchair racing star David Weir will try to break the world record for the fastest mile today - aiming to beat three minutes on the 60th anniversary of Roger Bannister's four minute mile.

He is racing as part of the Bupa Westminster Mile event - a one day festival of mile and track racing in the capital. Sir Roger will be there himself to watch the race and present prizes.

Mo Farah will fire the starting gun at some of the afternoon's races - before looking to claim another victory of his own in the Bupa London 10,000 race on Sunday morning.
