May I strongly advise any Tower Hamlets based swimmers either by school or home-address or both to register with the Tower Hamlets organiser email@example.com directly rather than wait to be invited. Please register by the middle of May 2017. The event is coordinated by the Tower Hamlets Youth Sport Foundation.
There are some great swimming events and the Aquathalon is great fun and consists of combined swimming and running. Youth Games swimming events are at the beginning of July. Please look this up at the Youth Games website.
