Among the most intense sports at the Winter Olympics are the bobsled events, or officially, "bobsleigh."

The bobsled events that most of us are familiar with involve what look like miniature rockets propelling down a man-made track at extreme velocities, often under the cover of a roof to protect the track from the elements.

But things were much different nearly 100 years ago when the sport was part of the first Winter Olympics in 1924, held in Chamonix, France.

Below is a look at just how much the sport has evolved through the years, with a lot of help from the IOC who collected video from many of the Olympiads. You can see that video here.
