Competitors stripped off to compete in Sochi today, with skiers competing in their vests and some athletes even using the snow to cool down as temperatures rose to 18 degrees celsius (64F) today. Sochi was warmer on Thursday than any of the last 10 cities to have hosted the Winter Games, while it was even warmer than Athens, who hosted the Summer Olympics in 2004. Forecasters predict that temperatures will not cool down until Saturday at the earliest, with Sochi on course to be the warmest ever Winter Games, surpassing Vancouver 2010.
