Cambs chairman Paula Durrant added: “The commitment, skill and overall fabulous team spirit of the Cambridgeshire county squad 2017 resulted in a phenomenal outcome and gave me immense pride.
“The conduct of these swimmers and their competitive attitude was inspirational and professional .
“I would also like to thank all the coaches at the clubs the team represented and the parents of the swimmers, without whom the squad members would not be able to train. I fully appreciated their support to the county giving up their family time to allow their swimmer to take part in such an event.”
