Kenyan-born Bahraini Rose Chelimo edged veteran Edna Kiplagat to win the women's marathon at the IAAF World Championships on Sunday. Kiplagat hit 40km a second ahead, but Chelimo kicked in the last 2km to win Bahrain's first medal in the event in 2hr 27min 11sec. Kiplagat, a two-time previous champion in 2011 and 2013, claimed silver seven seconds adrift, with American Amy Cragg taking bronze.
