"Canada's Marielle Thompson underlined her form as the leading ski cross racer this season with a dominant victory in the Olympic final.

"The 21-year-old led almost from start to finish to hold off team-mate Kelsey Serwa as the pair stretched clear of the other two skiers. French veteran Ophelie David, 37, took a shock fall at the back to leave Sweden's Anna Holmlund to coast home uncontested for bronze. Intermittent fog and drizzle added to the unpredictability of this engrossing sport, which as usual threw up thrills and spills aplenty. But there were worrying leg injuries requiring blood wagons off the mountain for Germany's Anna Woerner and Canadian Stephanie Joffroy in earlier rounds."

The measuring device comes out and confirms that Sweden's stone is marginally closer to the centre than China's. That means we will have a tie-breaking extra end, with China holding the hammer.

Agonising scenes in the curling. Sweden, trainling 4-3, are lying shot with one more stone to play. A single point for the Swedes will take us to an extra end. Two points would win it outright.

We are into the decisive tenth end of the men's curling bronze medal match with China leading Sweden 4-3.

It's a Canadian one-two in the women's ski cross final, with Marielle Thompson beating her compatriot Kelsey Serwa. The Canadians are quickest out of the blocks, with France's Ophelie David giving chase before wiping out on one of the final jumps. Serwa never looks like denying Thompson the gold.

And binds the mire like a rock;

When to the loughs the curlers flock,

Wi' gleesome speed."

The building was the only one in the city that was large enough and cold enough for the task.
