We welcome any swimmer (of age 18 and over) who’d like to come down to try out to see whether they are interested in joining up. It is you trying us out and not the other way round: there is no test to pass!
We do recommend that you are able to swim 400m (16 lengths) continuously and that you are willing to swim different strokes (although you don’t need to be an expert in all of them!).
Please contact us first to check about coming down for a trial: callymasters@gmail.com
