LOndon- Britain's Adam Peaty smashed the world record for the 100 metres breaststroke at the British Swimming Championships. The 20-year-old, who also holds the 50m world record, finished in 57.92 seconds, beating the 58.46 mark set by South Africa's Cameron van der Burgh. "I kind of surprised myself," Peaty said after becoming the first man to break the 58 seconds barrier. "I was going to wait until world championships to produce that time and I can't really believe it. The crowd really carried me home on the last 50 because it's a hell of a pain train. It's kind of surreal, there must be something in that lane four that really matters. I knew I could get 58 and I knew that if the heavens were on my side I could get a 58 low but to be the first person under 58 -- I have got no words."
