After leading for three out of the four heats in women's bobsledding, the American team of Elana Meyers and Lauryn Williams couldn't hold on for Olympic gold on Wednesday.

Instead, defending Olympic champions Kaillie Humphries and Heather Moyse, who competed as the Canada 1 team, came from behind on the fourth and final heat to beat Meyers and Williams by one-tenth of a second.

Fellow Americans Jamie Greubel and Aja Evans, who competed as the United States 2 team, won the bronze.

United States 3, made up of Jazmine Fenlator and Lolo Jones, finished 11th overall. Jones ran hurdles in the 2012 and 2008 Summer Olympics, narrowly missing a medal in both.

Williams was seeking to make Olympic history by becoming just the second Olympian to win gold medals at both the Winter and Summer Games, joining Eddie Eagan, who won gold in boxing at the 1920 Summer Olympics and gold in four-man bobsled at the 1932 Winter Olympics.

Williams won gold in the 4x100 meters relay at the 2012 London Games and also won silver in 2004.

Although Williams fell short of history, the U.S. teams made some together. Before Wednesday's medals, the U.S. had never won two Olympic medals in one women's bobsled race.

Meyers and Williams led after the first two heats on Tuesday with a combined time of one minute, 54.89 seconds, with Greubel and Evans in third at 1:55.45.

Meyers and Williams set a new track record at the Sochi bobsled course with a time of 57.26 on their first heat.

United States 1 gave up a bit of ground to the Canadians on their third heat Wednesday, finishing second behind them, and then finished with the third-best run on their fourth and final heat to drop back into second place.
