James Wilby from the United Kingdom came fifth.Peaty was elated with his victory and shouted "come On!" as he left his competitors wondering how they will beat him.The 26-year old, who had the 16 fastest times in the event, said that "it means the world to me." It is not about who is best all year, but who is the best on a given day. It's about adaptability and who wants it most."When it comes down it, I'm not racing for a moment, I'm racing myself.""I would like to thank my beautiful partner and my son for their support. This win was not mine. It was the British team and my family and close friends.
