Rosa Khutor (Russia) (AFP) - Former US Olympic 100m sprinter Lauryn Williams marked her debut as a winter Olympian on Tuesday by topping the opening heats of the women's bobsleigh in Sochi.
Williams, a silver medallist at the 2004 Athens Olympics and part of the 2012 gold-medal relay squad in London, was the brakewoman on USA-1, piloted by Elana Meyers.
"The nerves definitely overtook me. All day long, I've been nervous, well before we got here," Williams said.
"And I got on that line and I knew something good was going to happen because I was literally ready to jump out of my skin and that's a feeling I hadn't had in a while in track and field.
"It was good to have that feeling back and know what that means -- that means going fast."
Meyers, who won a bronze medal at the 2010 Vancouver Games, performed two consistent runs to clock a combined time of 1min 54.89sec and finish 0.23sec ahead of reigning champions, Kaillie Humphries and Heather Moyse of Canada.
"It feels pretty good but we've got a lot of work to do," Meyers said.
"It's not over. It's a battle. We're going to go back, get some food, get some sleep, rest up and be ready to go for tomorrow."
In her first run, two-time world champion Meyers set a new track record with a time of 57.26sec.
The USA-2 team of Jamie Greubel and Aja Evans are third with a time of 1min 55.45sec.
The third US team of Jazmine Fenlator and former US Olympic hurdler Lolo Jones, who was a controversial selection with some critics claiming she had been selected for her good looks and high media profile, failed to make it into the top 10.
They were 11th, at 1.84sec behind the leaders.
The medal winners will be decided after the third and fourth runs on Wednesday.
The times of all four runs are added together to determine the winner.
