The current world record for 100m swimming was set at the Paris Olympics by Chinese swimmer Pan Zanhle. He won gold with a new record time of 46.40 seconds. 

100 years ago, the world record was 57.4 seconds and was held by American swimmer, Johnny Weissmuller, who became better known as an actor as Tarzan in 12 films from 1932 to 1948. 

It took 100 years for the world records to fall by 20 seconds yet, according to Strava, my times have fallen not just 20 but 40 seconds in just two months as all my swim times today showed 100m laps of seven seconds.

I could put this down as a one off error but I was getting the same results on Monday too. I would swim 100m and, afterwards, find that it was either recorded around the four minute mark, or as 7 seconds. 

I thought I was swimming steady, but, Strava doesn’t lie. It uses complex sensors to check just how fast I was going and if it says I swum 100m in seven seconds then it must be right. 

Move over Tarzan, I’m King of the Pool now.
