Justin Gatlin ruined Usain Bolt's Farewell Party when the 35-year-old American won the World 100 meters title at World Athletics Championship.

As so often before Jamaican Bolt made a terrible start but this time he could not make it up as Christian Coleman, the 21-year-old American who beat him in the Semi-Finals, looked set for victory.

But former World and Olympic Champion Gatlin, who stumbled at the death to lose the 2015 World Final to bolt, timed his surge and dip to perfection to win in 9.92 seconds. Coleman took silver in 9.94 with bolt third in 9.95.

Ethiopian Almaz Ayana destroyed the field to win the 10,000 meters, finishing about 300 meters clear of her rivals.

The Olympic Champion began pulling away from the field after 10 laps, sweeping past back markers who were made to look sluggish in comparison.

She finished in 30 minutes and 16.32 seconds, well outside the World record she set in rio last year. Tirunesh Dibaba took the Silver Medal.

Lithuanian Andrius Gudzius finally fulfilled expectations to shock the big names in the discus and take gold with a second-round throw of 69.21 meters, the best of his life.

South Africa's Luvo Manyonga won the long jump title with a second round Leap of 8.48 metres.

Defending 1500 meter World Champion Genzebe Dibaba had to face an Agonising wait before she secured qualification for the final after a pair of closely contested Semi-Finals.
