Linford Christie is a Jamaican-born British former sprinter and athletics coach. He is the only British man to have won gold medals in the 100 metres at all four major competitions open to British athletes: the Olympic Games, the World Championships, the European Championships and the Commonwealth Games. He was the first European athlete to break the 10-second barrier in the 100 m and held the British record in the event for close to 30 years. He is a former world indoor record holder over 200 metres, and a former European record holder in the 60 metres, 100 m and 4 × 100 metres relay.

Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis.
