Gabby Logan presents live coverage of the 38th London Marathon as world-class runners and thousands of fundraisers compete in one of the world's most famous and colourful races.

In the men's elite race Great Britain's four-time Olympic champion Sir Mo Farah makes competes. His rivals include defending champion Daniel Wanjiru of Kenya, his compatriot Eliud Kipchoge and Ethiopia's Kenenisa Bekele.

Mary Keitany starts as favourite to win the women's race for a fourth time, a feat only the Norwegian Ingrid Kristiansen has ever achieved. The Kenyan is running with male pacemakers in her bid to beat Paula Radcliffe's world record. Keitany again goes head to head with three-time Olympic gold medallist Tirunesh Dibaba, who has never won in London.

Great Britain's David Weir set a new record of seven victories in the men's wheelchair race in 2017 and is back to defend his crown. In the women's race, 2017's winner Manuela Schar also returns and faces a daunting field that includes American great Tatyana McFadden.

Reporting along the 26.2-mile route are Colin Jackson, Steve Brown and Radzi Chinyanganya, while commentary is by Steve Cram, Andrew Cotter, six-time London Marathon wheelchair race winner Baroness Tanni Grey-Thompson and Paula Radcliffe, who set the women's marathon world record 14 years ago in London.
