Downhill skiers can go as fast as 140 kilometers per hour (85 miles per hour)--faster than the speed limit on most freeways! Their average speed is over 100 kph (60 mph). Even the air slows the skiers down at these speeds, so they crouch down to make themselves aerodynamic. There are three jumps on the course, where the skiers try to make their time in the air as short as possible. They train very hard to build strong bodies that can stand up to the fierce winds created by their speed. If they don't pay attention to all these things--their technique, condition, strength, and courage--they will not be able to shave fractions of a second from their times to become champion skiers.
