Roger Federer and Lindsey Vonn met in Jungfraujoch, Switzerland to play a tennis match two miles above sea level. The court was built on the Aletsch glacier — the largest glacier in the Alps.

Vonn said she surprised the 17-time Grand Slam champion with her skill on the court.

“I think Roger wasn’t expecting me to be that good at tennis. I’m not very good, still, but I had some good shots, and it was good to get a point.”
