Hi, Dont forget that there are football games at Wembley and the london marathon this weekend so I would avoid the A40 as this will be very very busy!! Come down the following route - M40, M25 (towards Heathrow), M4 right into central London along Cromwell Road. Turn right down earls court road and follow the one way system to the river. Then along embankment, cross vauxhall bridge, oval, camberwell. I do this route most weekends and find it the most straight forward.
