US paralympian Joshua George has narrowly beaten Britain's David Weir after a sprint finish in the men's wheelchair London Marathon today.
George won in 1:31:31. Weir was one second back, with Masazumi Soejima coming third in 1:31:33.
A runner who took part in the London Marathon completed 21 miles before realising the "slight pain" he felt was actually a broken hip.
The London Marathon brings together thousands of people raising money for charity - not to mention some rather unusual costumes.
Nearly 38,000 runners will hope to complete Sunday's London Marathon making it the biggest event in its 35-year history.
