Usain Bolt is a Jamaican sprinter who is widely regarded as the greatest sprinter of all time. He is the first person to hold both the 100 meters and 200 meters world records simultaneously. He is also the only sprinter to win three consecutive Olympic gold medals in the 100 meters. Bolt is known for his signature move of 'bolting' on the track, which is when he accelerates quickly and powerfully at the end of a race. This move has become synonymous with his name and is often referred to as the 'Bolt on a Track'.
