Congratulations to Hendrik van der Leest, who has just been confirmed to have set a new Dutch National age group record in 200m backstroke : Whilst swimming at Nationals in Sheffield, Hendrik broke the age group record for 14 year olds in the 200m backstroke by over 1 second.  The old record had stood firm since December 2007 at 2:11.99 and has now been sharpened to 2:10.92 on 29th July 2018, following Hendrik’s silver medal national swim. 
A great achievement by Hendrik.
