Usain Bolt traditionally wins three gold medals (100m, 200m and 4x100m) at major competitions, but his triumph at the 15th World Athletics Championships in Beijing can be classified as a miracle; his victories in the Chinese capital this year are perhaps more valuable than the triple victories, with a new world record, at the Beijing Olympics in 2008 and the World Championships in Berlin in 2009. The Jamaican sprinter was at his prime then and did not know what injuries were.

This season, however, due to injuries, Bolt only had six races in four days. With the best seasonal result of 9.87 sec in the 100m and 20.13 sec in 200m, he was an outsider in the expected duels with Justin Gatlin, who won more than 26 races this season in the 100m and 200m, and had his 100m personal best 9.74 sec.

However, when the Jamaican sprinter came out on the line, he was again the invincible Bolt. After his triumph in the 100m, 200m and the relay, he won three gold medal; he is the first athlete to complete a “triple triple” and now has a record 11 gold medals from the world championships.

Bolt was one of 13 world champions from the 2013 World Championships in Moscow who defended his titles in Beijing; the extraordinary achievements also include the “triple double” triumph for British Mo Farah in the 5,000m and 10,000m races; the Brit also won double golds at the London Olympics in 2012 and in Moscow in 2013.

Kenyan athletes had the highest number of medals won; they won seven gold, six silver and three bronze medals. Their great runners, who not only won the 800m and longer races, now triumphed in other disciplines; Nicolas Beth won the 400m hurdles.

Overall, this was a great tournament for Great Britain athletes, who won seven medals: four golds, one silver and two bronze and finished in fourth place in the medal’s table; Jessica Ennis-Hill won gold in the heptathlon and GB’s women and men both won bronze in the 4x400m relays, which was a big success on the last day in Beijing.

The women quartet were behind Jamaica and USA and the men were behind USA and Trinidad and Tobago. The medal was a special treat for Martyn Rooney, whose wife gave birth to their son during the Championships.
