Canada claim bobsleigh gold
Kaillie Humphries and Heather Moyse sealed Winter Olympics gold for Canada in the woman's bobsleigh at the Sanki Sliding Center.
American brake-man Lauryn Williams appeared on course to go into the record books as only the second person to top the podium in both the Summer and Winter Games as she and pilot Elana Meyers held a comfortable lead overnight.
But an advantage of 0.23seconds was more than halved by Humphries and Moyse, who then used all of their experience to produce a storming final run that Meyers and Williams could not match to triumph again by 0.10seconds.
Meyers and Williams, who won gold in the 4x100metres at London 2012, had led after all three stages but their nerve seemed to dessert them at the crucial stage and they had to settle for silver, with fellow Americans Jamie Greubel and Aja Evans earning bronze.
British pair Paula Walker and Rebekah Wilson fell short of their aim of a top-10 finish as they finished 12th, 1.87secs adrift of Humphries and Moyse overall.
