Van der Burgh breaks 50m breaststroke world record

Van der Burgh, who is defending his title, clocked an official time of 26.62sec to shave 0.05sec off his own record he set at the 2009 championships in the era when the performance-enhancing neoprene suits were still permitted.

Peaty had swum exactly 26.62sec at the European championships in Berlin last August, but his time has still not been ratified by swimming’s governing body FINA.

Van der Burgh, the Olympic 100m champion, lost out to Peaty on the wall in Monday’s world championship final over the same distance.

The rivals are set to battle again over the shorter distance in Tuesday night’s semi and Wednesday’s final.

“I am really happy after the bitter-sweet disappointment of last <g data-gr-id="42">night,</g> when I didn’t get the luck of the touch. But I guess I had it on Tuesday,” said Van der Burgh.

“We are all so close, it’s not going to be a one- or two-horse race, there are a lot of guys in the mix and it’s going to very tight.”

<g data-gr-id="38">Peaty</g>, who was second-fastest into the semi-finals at just 0.06sec slower than the South African in his heat, admitted he was confused as to who held the world record after Van der Burgh matched his Berlin time.

“It will be nice to get out there tonight with my full game head on to focus on the race,” he said.

“I am fully capable of going faster than... my old, well, <g data-gr-id="39">equal</g> world record.”

Slovenia’s Damir <g data-gr-id="41">Dugonjic</g> (26.70) and Kevin Cordes of the USA (26.93) also posted fast times going into the semis.

Australia’s Christian Sprenger, who won silver in the event two years ago in Barcelona, missed the semis by just 0.03sec at 27.54.

This is the fifth time a world record has been broken in Kazan and it is the first men’s record to fall at <g data-gr-id="47">a world championships</g> since 2011. Sweden’s Sarah Sjostrom broke the women’s 100m butterfly record twice in the space of 24 hours en route to retaining her world title on Monday here.
