The Hertsmere Flyers enjoyed great success at the Luton short course gala last weekend.
There were two new regional times set, six age-group records broken and 38 personal bests, with seven squad members recording personal bests in each of their races.
Joshua Foreman set new record regional times in 100m and 200m backstroke, with his time in the 200m also an age-group record.
Alicia Slater recorded personal bests in each of her eight races, setting age-group record times in the 100m backstroke and freestyle and the 200m backstroke.
Further club and age-group records were set by Chloe Jacobs in the 100m and 200m backstroke classes respectively.
Also impressing was Portia Nicholas-Jago, who managed to take an incredible 29 seconds off her personal best time in the 400m freestyle.
Acting head coach Tom George said: "I thought the application and effort put in by all the swimmers over both days was excellent and hopes this is all carried forward in to training over the coming weeks with future galas coming up for the club."
