Usain Bolt

Usain St. Leo Bolt, OJ, CD (/ˈjuːseɪn/; born 21 August 1986) is a Jamaican sprinter. Regarded as the fastest person ever timed, he is the first man to hold both the 100 metres and 200 metres world records since fully automatic time measurements became mandatory in 1977. Along with his teammates, he also set the world record in the 4×100 metres relay. He is the reigning Olympic champion in these three events, and the first man since Leonidas of Rhodes to win six Olympic gold medals in sprinting, and an eleven-time World champion. He was the first to achieve the "double double" of winning 100 m and 200 m titles at consecutive Olympics (2008 and 2012), and topped this through the first "double triple" (including 4×100 m relays).

Although gaining worldwide popularity for a sprint double victory at the Beijing Games, Bolt has had more victories as a 200 m runner. While he had not won any significant 100 m title prior to the 2008 Olympics, he had won numerous crowns in the 200 m event at the youth, junior and senior levels. Further, at the 2013 World Championships in Moscow, Bolt completed a hat-trick of 200 m world titles by winning his third straight gold in the event. His 2009 record breaking margin for 100 m, from 9.69 seconds (his own previous world record) to 9.58, is the highest since the start of fully automatic time measurements.

2015 World Championships in Athletics

The 15th World Championships in Athletics were held 22–30 August 2015 in Beijing, China. 43 nations won medals, 144 of which were awarded. Kenya topped the medal table for the first time, with 7 gold, 6 silver and 3 bronze medals. The United States won 18 medals, six gold, six silver and six bronze, which was the highest tally. Host nation China, finished 11th on the medals table, while Russia, the overall winner and host in 2013, finished ninth.

205 IAAF member countries and territories participated, two more than in 2013, with new IAAF member, Kosovo, making its debut. South Sudan was also set to participate for the first time, but its sole athlete did not show up in Beijing.

Eritrea won their first world title at these championships, with Ghirmay Ghebreslassie winning the men's marathon.

The event was the largest sporting event to take place at the Beijing National Stadium ("Bird's Nest") since the 2008 Summer Olympics.

Bidding process

When the seeking deadline passed on 15 March 2010, three candidate cities (Beijing, London and Chorzów) had confirmed their candidatures. London then withdrew citing that they didn't want to seem to be biased towards the bids for the Olympic Stadium by committing themselves to an athletics event, as the host for this event was to be announced before their 2011 stadium bid deadline. London then stated that they would bid for 2017 and had the blessing of the IAAF to do so. The IAAF announced Beijing as the winning candidate at the IAAF Council Meeting in Monaco on 20 November 2010. The Council of IAAF approved the dates of 22 August until 30 August 2015.
