Carnforth Otters swimmers were in action at the Inter Association competition in Liverpool.
Holly Salisbury, Aimee Banks, Thomas Dugdale, Sunni Rich and Connor White swam for North Lancashire while team mates Emily Reay, Ella Mounsey and Hannah Edwards were all selected to swim for Cumbria.
Holly was in fine form with two impressive personal bests in both the 100m and 400m freestyles.
Aimee rose to the challenge magnificently by shaving two seconds off her personal best in a close race in the 100m backstroke.
Thomas competed in the 100m butterfly and swam really well to set a new personal best.
Connor narrowly missed on a personal best in the 50m breaststroke and stepped up from reserve to swim in the 200m breaststroke at the last minute.
Sunni put in a solid performance in her 400m freestyle and was close to her personal best.
Emily swam close to her personal bests in each of her five events.
It was an excellent performance considering she had been injured three weeks prior to the competition and had been unable to train.
Ella had a superb couple of days and managed to get personal bests in each of her five events, knocking eight seconds off her 200m butterfly time.
Hannah also swam well, recording personal bests in each of her four events.
Times tumbled when she sliced six seconds off her 200m freestyle and nine seconds off her 200m breaststroke times.
