Downhill racers are athletes who compete in a variety of sports that involve going downhill. Skiiers, who use skis to travel down a mountain, are one type of downhill racer. Luge riders, who ride a small sled down a track, and sledders, who use a sled to go down a hill, are also downhill racers. Finally, bobsled teams, which consist of four people riding a sled down a track, are also considered downhill racers.
