Athletics: Women’s Marathon
11:00am BBC1, BBC Olympics 3
The clear favourite is the Kenyan, Mary Keitany, who won this year’s London Marathon. Her main rivals - on a slightly curious course that comprises three laps, taking in the City of London, the Embankment and St James's Park - should be Tiki Gelana of Ethiopia, Lilia Shobukhova of Russia, Edna Kipligat of Kenya and Shalane Flanagan from the US. British hopes rest on Mara Yamauchi and Freya Murray.
