"London will be amazing. Having experienced what the home crowd was like for the Chinese, it's going to be awesome. I walked out for one of my finals [at the trials] with my headphones on trying to get in the zone. I had my music up ["Monster" by Paramore and "Me and You" by Nero] so couldn't hear the noise but I could feel it. It was going through your chest, it was so loud – booming. You walk taller. It makes a difference and it does make you swim faster."
