bobsleigh

Bobsledding is a winter sport where teams slide down an ice-covered track on a sled called a bobsled or bobsleigh. The sport originated in the 1880s in New York and the Swiss Alps, with the first organized competition held in 1898.1

Bobsleds are typically large, metal sleds with two pairs of runners, a steering wheel, and a hand brake. They can carry one, two, or four people. Competitions take place on tracks similar to those used for luge and skeleton sledding.21

The name "bobsledding" comes from the technique of bobbing back and forth to increase speed. Athletes sprint to push the sled at the start, then jump in. The driver steers, and the brakeman operates the brake after crossing the finish line. Speeds can reach up to 90 miles per hour.13
