Hannah Miley won Great Britain's first gold medal at the World Short-Course Championships when she held off Olympic champion Ye Shiwen in the 400 metres individual medley in Istanbul.
The 23-year-old was fastest into the final although she fully expected a different race at the Sinan Erdem Dome given Olympic champion Ye had apparently held back on the freestyle leg.
Fourth at the halfway stage, Miley produced a superb breaststroke leg to move into the freestyle in first place. As expected, Ye came back strongly on the freestyle leg but Miley held her off to win in four minutes 23.14 seconds, a championship record.
Miley said: "A lot of top athletes aren't here so for me I see it as an opportunity and any opportunity I see I try and take it.
"So for me I was aiming for it to be a confidence booster for both myself and my dad and what we are doing this season.
"Not only were we trying to chase placings, but also to do a really good time which I was really happy with.
"But the main thing is long-course (50m) swimming so I am really happy with what I've done, but for me I am not going to be happy with it until I can prove I can do it long course as well.
"Hindsight is a great thing and lots of people have cliches and I was genuinely was happy with that swim, but for me I probably wouldn't be the athlete I am standing here today doing those times if the Olympics hadn't have happened."
