Britain's six-time winner David Weir was beaten by Swiss rival Marcel Hug in a thrilling sprint finish to the London Marathon wheelchair race.
Hug, who won last weekend's Paris Marathon, proved strongest, clocking one hour 32.41 seconds for his first win in London.
Weir was a second behind Hug with South African Ernst van Dyk in third.
American Tatyana McFadden set a new course record of 1:45.11 to defend her women's title.
McFadden is back wheelchair racing after winning a silver medal at the Sochi Winter Paralympics.
She finished a minute and a half clear of Switzerland's Manuela Schar and Japan's Wakako Tsuchida with Britain's Shelly Woods sixth (1:54.52).
