• Skeleton is a Winter Olympics sport that dates back to the 1880s.
• Events take place on a track made of ice. In Pyeongchang, the skeleton track is 1,376 meters long. 
• Skeleton athletes push sleds as fast as they can, then jump on and speed head first down the track, using minor shifts in body weight to steer.
• They can slide at speeds greater than 90 miles per hour. 
• It's really rough on the body.

Skeleton was born in Switzerland in the late 1800s.

Athletes hurtle down the track — and it's harder than it looks.

To TV viewers, the ride might look smooth. For racers, it's anything but.
