Swimathon, the world’s biggest fundraising swim, has been encouraging swimmers the length and breadth of the UK to swim a distance challenge since the very first event 31 years ago. Since then, Swimathon's mission of uniting swimmers around challenges and fundraising has prompted more than half a million swimmers to take part at their local pool and raised more than £48 million for charitable causes.
