The London Marathon was "tinged with sadness" after a man collapsed and died at the finish line, the event's organiser has said.
The 42-year-old man, who has not yet been identified, collapsed immediately after finishing the race but later died in hospital.
"We did very unfortunately have one death of a runner, who had finished and our thoughts are very much with the friends and family of that runner," Hugh Brasher, race director of the Virgin Money London Marathon, said.
"Overall it was a fantastic day, but it always is tinged with a little bit of sadness when something like that happens."
A female competitor from Sierra Leone, who finished 20th in the women's race, has also gone missing.
