Okayo for London Marathon
Former London marathon champion Margaret Okayo of Kenya will take part in this year's race on April 23, organisers said on Monday. Okayo won the 2004 London race after finishing first in the 2003 New York marathon. American Olympic bronze medallist Deena

Britain's world champion and world record holder Paula Radcliffe is favourite to retain her title.
