Mo Farah will target his fifth straight victory at the 2013 Bupa London 10,000 road race today.
He heads an elite field containing some of Britains finest distance runners.
The double Olympic champion is a regular at this 10km central London road event since it started in 2008.
His winning time three years ago of 27 minutes 44 seconds remains the mens course record.
Last year he chose to cruise home in a relatively modest 29:21 as he geared up for a glorious summer which climaxed at the Olympic Games last August when he won gold at 5000m and 10,000m.
