Waxing and filing for Sochi ski gold

An edge that is too sharp or the wrong kind of wax: that kind of detail can make the difference between gold, a fourth place or a crash in the alpine skiing in Sochi.

As racers fly down icy courses at more than 130 kph, their equipment needs to be finely tuned to fit conditions on the slope and the weather.

And in Rosa Khutor, the mountain venue where all the Olympic ski events are taking place, that has been quite a challenge over the past 10 days.
