It has finally happened, after all this time, this is one of the most long-standing world records of modern times, when it was stood by Britta Steffen on 2/8/2009 with a time of 23:73; it has now progressed to 23:67 from Sarah Sjostrom at the 2017 World Championships in Budapest. Sarah Sjostrom also took a margin of 0.78 seconds off the 50m butterfly. This beats the 0.53 seconds gap Adam Peaty achieved in the 50 breast. 0.78scds is a huge margin for a 1 lap race.
Commentators remarked that Britain does not have a sufficient sprint training program. Well perhaps the LAC offers an ideal venue for that purpose. British sprint swimmers have to train in Turkey because Britain has no dedicated sprinter program.
