Olympic racers are athletes who compete in various winter sports events at the Olympic Games. These include sleds, bobsleds, LUGES, and SCULLS. Sleds are vehicles with runners that are used to travel over snow or ice, and are typically pulled by horses or dogs. Bobsleds are a type of sled that is designed for two or more people to ride down an icy track. LUGES are one-person sleds that are steered by the rider's body movements. SCULLS are boats propelled by oars, and are used in rowing competitions.
