Dina Asher-Smith admitted her historic gold medal has been two years in the making after she stormed to 200m victory at the Athletics World Championships.
With many of the top medal contenders pulling out or skipping the event, Asher-Smith proved the class act in the Doha field, powering home in a national record 21.88 seconds to add to the silver she won in the 100m on Sunday.
Brittany Brown of the USA grabbed the silver in 22.22 while Switzerland's Mujinga Kambundji completed the podium by grabbing bronze in 22.51.
Asher-Smith came fourth in the 200m in London two years ago after battling back from a broken foot and revealed she and coach John Blackie have been preparing ever since.
"When I came fourth by a tenth of a second and almost did it he looked at me and said, 'the next one is going to be yours'," said the 23-year-old.
"I said, 'we have to work towards it, we have to make sure that when I stand on the line in two years' time I'm in a position to do that'.
"It means so much to have done that in the 200m but to have gone well in the 100m, an event I have not run at this level before, to be up there with the best women in the world means so much to me."
Asher-Smith also admitted she has already turned her attention to next year's Olympics in Tokyo.
She added: "The Olympics is less than a year away, we have already been thinking about it. I don't think there's any time we're not thinking about the Olympics.
"Doing well in Doha was part of the plan and in thinking about Doha you're thinking about the Olympics as well."
Poland's Pawel Fajdek was again in a class of his own as he claimed a fourth consecutive hammer world championship by unleashing the only effort over 80 metres.
On his fourth attempt, Fajdek put down his golden marker with a throw of 80.50m that no one could come close to matching.
The fight for the remaining medals was much tighter as Frenchman Quentin Bigot snatched the silver with a toss of 78.19, which was one centimetre better than Hungary's bronze medallist Bence Halasz.
Grant Holloway of the United States blazed to his first 110 metres hurdles world title in a dramatic race in which defending champion Omar McLeod fell.
The 21-year-old Holloway, who came into the championships with the season's fastest run of 12.98 seconds, smoothly glided through 10 hurdles to cross the line in 13.10, five hundredths of a second ahead of Sergey Shubenkov.
Favourite to defend his title, Jamaican McLeod came out of the starting blocks fast but his race quickly turned sour as he knocked down hurdles and tumbled to the track before reaching the finish line.
McLeod's problems seemed to upset Diamond League champion Orlando Ortega in the next lane and he finished fifth in 13.30 seconds. Bronze went to European champion Pascal Martinot-Lagarde.
