Bobsleigh or bobsled is a winter sport in which teams of two or four make timed runs down narrow, twisting, banked, iced tracks in a gravity-powered sled. The timed runs are combined to calculate the final score.

The various types of sleds came several years before the first tracks were built in St. Moritz, Switzerland, where the original bobsleds were adapted upsized luge/skeleton sleds designed by the adventurously wealthy to carry passengers. All three types were adapted from boys delivery sleds and toboggans.

Competition naturally followed, and to protect the working class and rich visitors in the streets and byways of St Moritz, hotel owner Caspar Badrutt, owner of the historic Krup Hotel and the later Palace Hotel, built the first familiarly configured 'half-pipe' track circa 1870. It has hosted the sports during two Olympics and is still in use today.

International bobsleigh competitions are governed by the Fédération Internationale de Bobsleigh et de Tobogganing (FIBT). National competitions are often governed by bodies such as the United States Bobsled and Skeleton Federation and Bobsleigh Canada Skeleton.

Jeremy Charles Robert Clarkson (born 11 April 1960) is an English broadcaster, journalist and writer who specialises in motoring. He is best known for his role on the BBC TV show Top Gear along with co-presenters Richard Hammond and James May. He also writes weekly columns for The Sunday Times and The Sun.

From a career as a local journalist in Northern England, Clarkson rose to public prominence as a presenter of the original format of Top Gear in 1988. Since the mid-1990s, Clarkson has become a recognised public personality, regularly appearing on British television presenting his own shows and appearing as a guest on other shows. As well as motoring, Clarkson has produced programmes and books on subjects such as history and engineering. From 1998 to 2000 he also hosted his own chat show, Clarkson.

His opinionated but humorous tongue-in-cheek writing and presenting style has often generated much public reaction to his viewpoints. His actions both privately and as a Top Gear presenter have also sometimes resulted in criticism from the media, politicians, pressure groups and the public.
