Join us!

If you are looking to join Castle Tri and haven’t attended a session yet, we recommend you give us a try first and make sure the club is for you. The first session is free, and if you would like to join, membership costs £25 for the year and each swim session is £5 to attend. Membership renawal for 2020 will be opening soon and therefore to join us for the remainder of 2019 is free of charge - just pay for your swim sessions.
