A group of 12 women and a man, ranging in age from 22 to 67, will attempt the first 16-mile official swim from Arran to Troon at the end of the month. The relay swim, which is expected to take the two teams a gruelling 12 hours to complete, will raise funds for the RNLI and local Ayrshire charity, the Jo Walters Trust.

The mainland group, who call themselves the Arran TrooNautics, are mostly all new to open-water swimming but have trained hard for the past year to get to the point where their coach and experienced cross-Channel swimmer, Chris Sifleet, is confident they can make the crossing.
