LONDON (Reuters) - Kenya's Olympic silver medalist Priscah Jeptoo won the women's London Marathon title in an unofficial time of two hours 20 minutes 15 seconds on Sunday.
World champion Edna Kiplagat was runner up for the second successive year and Japan's Yukiko Akaba took third.
Jeptoo had been leading with Kiplagat at 30 km but began to increase her pace to leave her rival trailing and eventually won by over a minute.
Ethiopia's Olympic champion and pre-race favorite Tiki Gelana dropped off the pace after colliding with a wheelchair athlete at a drinks station at 15 km.
