The 44th National Arena League Final took place on Sunday 21st April at Cardiff International Pool. The top clubs from the 6 regional leagues and the 4 best runners-up competed for the national title; City of Sheffield and City of Leeds represented the North East League. Swimmers competed in under 11s, 13s, 15s and open age groups.

A small group of swimmers from AGN, Senior Elite and Masters squads competed in the NER Youth and Senior Championships in Sunderland over the weekend on 4th/5th May. With the exception of the distance and relay events, there were heats and open finals for each event. Given the small number of swimmers making the trip, COSSS was well represented in the top ten finishers.
