Late 2021, five swimmers from the Hertfordshire and Essex High School competed at the Secondary Schools National Team Relay Championships at the London Aquatics Centre. This event is the longest running championship series organised by the English Schools Swimming Association (ESSA) and is open to secondary school aged swimmers from across England.
The H&E swimmers had qualified for the National event a month earlier at the East & South East Division championships, coming 2nd in the 4x50m Medley relay and 3rd in the 4x50m Freestyle Relay.
In a National competition dominated by the top English specialist swimming boarding schools, the swimmers, who are also all members of BSSC, gave excellent performances with the 4x50m freestyle team finishing 18th and the 4x50m medley team reaching the national final where they came 9th overall in a time of 2:14.81. It was a highly competitive final with only two hundredth of a second separating 7th to 9th places.
