Bolt, the son of grocers in Jamaica’s rural Trelawny parish, excelled as a cricket fast bowler in his preteen years. He developed a deep affection for the European football (soccer) teams Real Madrid and Manchester United, but his school coaches steered him toward track and field. Bolt first marked himself as a track prodigy at the 2002 world junior championships. In that meet, racing before a crowd of 36,000 in Jamaica’s National Stadium in Kingston, Bolt—just 15 years old at the time—won gold in the 200 metres, becoming the youngest-ever male world junior champion in any event. At age 16 Bolt cut the junior (age 19 and under) 200-metre world record to 20.13 sec, and at 17 he ran the event in 19.93 sec, becoming the first teenager to break 20 seconds in the race. However, hampered by a hamstring injury, he failed to advance beyond the 200-metre heats at the 2004 Olympics in Athens and placed last in the 2005 world track-and-field championships final.
