Winter Olympic champion Lizzy Yarnold has revealed how her celebrations were cut short by the need for her to take a regulation drug test.
The 25-year-old became Team GB's first gold medallist of the Sochi Games by winning the women's skeleton by an emphatic margin in Russia last Friday.
However, she was not allowed to rejoin her friends and family until after she had given a urine sample, and the party mood had been dampened by the time she had forced herself into providing one.
Speaking on The Jonathan Ross Show, she said: "I competed so late in the day, the first thing you've got to do after any competition are fun things like drug testing.
"I was in drug testing trying to provide my urine sample for two hours. I was knocking back loads of glasses of water just so I could complete the urine test.
"Then I went back to the athlete village, it was midnight by this time."
Yarnold's victory ensured that Team GB retained the women's skeleton title following Amy Williams's triumph at Vancouver 2010.
