Sea swimming is the great leveller; we're all the same in a pair of togs. No one minds who you are or what you've done; the question is 'are you getting in?' Popular for centuries, sea swimming has had a recent surge in interest with a growing community now taking the plunge. Brendan Mac Evilly and Michael O'Reilly, enthusiastic members of this bathing fraternity, chart their adventures in 43 of Ireland's most popular places to swim. Part guidebook, part travelogue, part analysis of our relationship with the sea, At Swim explores the thrills, fears and joys of sea swimming.
