Switzerland native and 17-time Grand Slam champion Roger Federer challenged U.S. Olympic skier Lindsey Vonn to a tennis match, atop a mountain.
Federer and Vonn took to the court on Aletsch Glacier in Switzerland, just below the Sphinx summit in Jungfraujoch, to celebrate the opening of the LINDT Swiss Chocolate Heaven, a shop at 3,454 metres above sea level on Jungfraujoch.
