Swimathon began in 1986 with a London-only initiative, organised by the Guild of London Bath Managers to encourage pools to get more people swimming. The launch of the annual event was in 1988 and since then Swimathon has seen over 700,000 participants at over 1,200 different pools across the UK, getting involved, swimming for the challenge and raising money for charity. Swimathon attracts swimmers of all levels from experienced Swimathon participants to complete novices, this is reflected in the different challenges available to those taking part.
