Bobsleigh or bobsled? Well, both are correct. Generally, in Canada we say "bobsledders who sled on bobsleds," while bobsleigh is the official name of the Olympic sport.
Most bobsleds are built to hold two to four athletes, but one-person bobsleds — monobobs —are starting to gain in popularity. The 2016 Youth Olympic Games in Lillehammer featured monobob events.
Bobsleigh was invented by the Swiss in the late 1860s, when they attached two skeleton sleds together and added a steering mechanism to make a toboggan.
The original wood sleds were replaced by steel ones, which became known as "bobsleds" because of the way the athletes bobbed back and forth to increase their speed at the start. Modern sleds are made of fibreglass and steel.
To steer a sled, the driver pulls a rope with their right hand to go right or a different rope with their left hand to go left.
Each bobsled team gets to go down the course four times — called "heats" — and the total time of all four runs is what determines the ranking.
