Brit Williams on course for gold

Britain is on course to win its first gold medal as Amy Williams has the halfway lead in the women's skeleton.

The Brit set a new track record too, of 58.83 seconds on her first run, and that plus her second run gives her a lead of 0.30 seconds.

It might not sound like much time, but in a race as fast as this one it's considered a very strong lead.

You'll have to wait until the weekend to see if she clinches the top spot - the race finishes late on Friday night.

Amy's team-mate Shelley Rudman moved from 11th to joint seventh in the same race.

Amy Williams has broken a track record with her skeleton performance

Shelley won silver in the Winter Olympics four years ago, and she was unhappy with her first run calling it "terrible".

Amy said of her performance: "I've got to keep level headed... and sleep well. And thanks to everyone at home for staying up late to watch!"
