International Association of Athletics Federations (IAAF) President Sebastian Coe has pledged not to abandon attempts to introduce lifetime bans for convicted doping cheats following Justin Gatlin's World Championships 100 metres victory here last night. 

Justin Gatlin picked up the script, ripped it in half and then tore it into shreds by stunning Usain Bolt to win the men's 100 metres crown at the International Association of Athletics Federations (IAAF) World Championships here tonight.

Usain Bolt offered evidence here tonight that he can finish his career at the International Association of Athletics Federations (IAAF) World Championships on the gold standard.

For a few seconds, Ryan Bailey - running the final leg for the United States men's 4x100 metres team at the London 2012 Olympics - could sense gold at the end of the track. 

It’s not as if it was the first time Usain Bolt has been upstaged.

“The Russians are coming” was a popular buzz phrase back in the days of the Cold War.

Christian Coleman’s rising ambitions in the 100 metres were checked on the second day of the USA Track and Field World Championships trials in Sacramento as he was narrowly beaten to the title by 35-year-old Justin Gatlin, who clocked 9.95sec.

Christian Coleman gave another display of sizzling pace as he won his 100 metres heat at the USA Track and Field (USATF) World Championship trials in Sacramento in 9.93sec on a day which saw Galen Rupp lose out in the men's 10,000m.

The United States Track & Field Championships that start in Sacramento tomororw are due to feature 23 Olympic gold medallists - but a new wave of talent could mean many familiar names fail to qualify for this summer's International Association of Athletics Federations (IAAF) World Championships in London. 

Jamaica’s Olympic 100 and 200 metres champion Elaine Thompson brought home the baton with ease to earn the 4x200m title at the third International Association of Athletics Federations World Relays at the Thomas Robinson Stadium in Nassau in an event record of 1min 29.04sec on a night when her compatriots in the men’s 4x100m, the world and Olympic champions, crashed out in the heats.

A third and innovative edition of the International Association of Athletics Federations (IAAF) World Relays this weekend in the Bahamas will involve an Athlete Refugee Team wearing on-body cameras, a new mixed 4x400 metres relay and drone footage.

After anchoring Jamaica home to gold in the men’s 4x100 metres, and thus completing a perfect 100m/200m/relay record in the last three Olympics, Usain Bolt diverted from his now customary lap of honour to kneel at his finishing point in lane three, bend down to the track and kiss the Games goodbye.

Jamaica’s Elaine Thompson bucked the trend on a huge night for United States women athletes as she became the first woman since Florence Griffith-Joyner at Seoul in 1988 to win the sprint double at the Olympics, winning the 200 metres in 21.78sec after holding off the world champion Dafne Schippers of The Netherlands, who clocked 21.88.

A stupendous night of athletics here produced the result that most people wanted to see as Usain Bolt beat Justin Gatlin to earn a third consecutive Olympic 100 metres title in 9.80sec, but even that huge feat was overshadowed by the performance of South Africa’s Wayde van Niekerk as he won 400m gold from lane eight in a world record of 43.03, breaking Michael Johnson’s 17-year-old mark.
