Speed Riding 

A growing sport invented by the French, it combines skiing and paragliding to exhilarating effect. The concept is simple, start with a gentle ski and when you're feeling ready, yank on a cord and you go up up and away, before gently steering yourself back to land on the snow. 

The kit consists of a pair of skis, helmet, goggles and a specially-designed canopy that is closely related to the traditional paragliding wing. It's the closest you can get to flying and skiing at the same time if that isn't too weird a sensation to imagine.
