Sue Barker hosts continued coverage of the 30th London Marathon.Follow the pace of all the elite races as the competitors race through the streets of the capital. Kenya's Olympic champion Sammy Wanjiru took the men's title in 2009, winning in London for the first time in the absence of three-time champion Martin Lel. Wanjiru will defend his title, but Lel is back as well as the second fastest marathon runner of all time, Duncan Kibet. Kurt Fernley and Amanda McGrory emerged victorious in dramatic finishes to both the men's and women's wheelchair races in 2009; further excitement is expected again this year. Much attention will focus on more than 30,000 'fun' runners whose main aim is just to finish but between them they will raise more than 50 million pounds for charity.
