Live coverage as some of the world's top male cyclists, including British stars Bradley Wiggins and Mark Cavendish, compete in Britain's biggest one-day race.
The 125-mile route begins at Horse Guards Parade and passes through eight London boroughs. It then snakes its way through the Surrey countryside, retracing part of the route made famous by both the road race and time trials at the 2012 Olympic Games, before riders return to central London, crossing the finish line at the Mall.
Britain's Adam Blythe was the surprise winner of last year's race after beating his rivals in a sprint finish.
