Great Britain's Hannah Miley has said that she must swim faster than ever before if she hopes to claim the gold in tonight's 400m individual medley final.
The 22-year-old Scot booked her place in the next phase by producing the sixth-fastest time in the heats, finishing in 4:34.98.
"I was really happy - it was my fastest swim in a heat, so that's great. I have got to see what I can do now for the final," she told BBC Sport.
"I've just got to swim the race of my life. I can only control what I can do. I can't control how fast other people are going to swim.
"Before a race, my dad gives me a hug and says 'I love you'. It's great to be swimming not just for myself, but for my family, him and his hard work."
Miley, who picked up silver at last year's World Championships in Shanghai, will compete in the women's 400m individual medley final at 8.09pm this evening.
