Competing in the 16 and 17 year age group for Lancashire, Josh Thompson had a superb swim in the 100m breaststroke, finishing second in a personal best time of 1.02.58 - the fifth fastest time ever for a 16-year-old.
Josh also competed in the medley team relay, with a 50m breaststroke leg of 28.34 helping the team to first place in a time of 1.42.52.
He also swam in the 6 x 50m freestyle mixed relay team.
Holding off Somerset, Yorkshire and Middlesex all day, Lancashire were crowned 2014 champions.
Two Otters also represented Cumbria at the event, Hannah Edwards and Ella Mounsey, both 13.
Hannah swam right on her personal best time, 1.24.95, to finish 20th in the 100m breaststroke and swam the breaststroke leg, 38.99, in the medley team relay as the team also finished 20th.
Ella had to wait for the day’s final event, the 6 x 50m freestyle mixed relay. It was worth the wait though as she pulled off an excellent swim of 30.20.
Having been promoted last year Cumbria have been relegated back to Division Two after finishing 20th.
