The 2002 World Junior Championships were held in front of a home crowd in Kingston, Jamaica, and Bolt was given a chance to prove his credentials on a world stage. By the age of 15, he had grown to 1. 96 metres (6 ft 5 in) tall, and he physically stood out among his peers. He won the 200 m in a time of 20. 61 s, which was 0. 03 s slower than his personal best of 20. 58 s, which he set in the 1st round. Bolt's 200 m win made him the youngest world-junior gold medallist ever. The expectation from the home crowd had made him so nervous that he had put his shoes on the wrong feet, although he realized the mistake before the race began. However, it turned out to be a revelatory experience for Bolt, as he vowed never again to let himself be affected by pre-race nerves. As a member of the Jamaican sprint relay team, he also took two silver medals and set national junior records in the 4×100 metres and 4×400 metres relay, running times of 39. 15 s and 3:04. 06 minutes respectively.
