The Swimathon Foundation History

The start of Swimathon

An initiative of pool managers in London, the pilot Swimathon event took place in 1986. It aimed to replicate the success of the London Marathon as a way of encouraging Londoners to take up regular exercise and inspire swimmers to use their local swimming pools to train for the challenge of 5,000 metres.

Two years later, in 1988, Graham Batterham teamed up with Olympic Gold Medallist Duncan Goodhew MBE and together, working alongside pool managers, charities and sponsors, turned Swimathon into the national event it is today.

“The success of the pilot event clearly showed Swimathon had enormous potential to achieve the twin objectives of promoting swimming as a healthy sport and raise money for good causes. By linking with Great Ormond Street’s ‘Wishing Well Appeal’ and gaining the support of Princess Diana in that year, it gave the new concept of Swimathon the springboard it needed to become the national event it is today”
Graham Batterham, Advisor to the Trustees

Thanks to the support of major sponsors, in particular BT (1991 – 2001), Swimathon was able to grow and develop nationally and in 1997 The Swimathon Foundation was formed to secure the events future and administer the charitable funds raised. Since then it has only continued to grow, raising £2.34 million in 2016.

The birth of The Swimathon Foundation

Founded in 1997 The Swimathon Foundation, owners of the Swimathon event, brings together swimmers of all ages and abilities with two simple aims: To spread the joys and benefits of swimming whilst raising money for some of the UK’s most deserving charities. What started out as an initiative to increase swimmer numbers in local authority pools has grown over the years into the world’s largest fundraising swimming event, bringing together hundreds of communities to promote the benefits of swimming and raise vital funds for many national charities.

Looking to the Future

The Swimathon Foundation has exciting plans for the future of the event and in the last few years had announced a series of partnerships to expand the size and reach of The Swimathon Foundation including:

  • A partnership with Swim England (formerly the Amateur Swimming Association) to jointly develop and promote a School Swimathon. School Swimathon will aim to promote swimming to children under the banner ‘Swim your Best’. In 2017 School Swimathon saw over 12,000 pupils involved, with 81% of pupils improving their swimming distance during the campaign.
  • Following Swimathon’s recent 30th anniversary which has so far raised over £1.5 million, The Swimathon Foundation announced that Cancer Research UK and Marie Curie will be the official charity partners of Swimathon for the next four years.
  • A joint partnership with the Swimming Trust and British Swimming to assist in the promotion and administration of the Swimathon Community Grants Scheme.
  • A new four-year contract with its Event Management contractors Limelight Sports to continue to develop the Swimathon event experience with our long-standing delivery partnership.
  • The launch of Open Water Swimathon in September 2017 with a pilot event taking the successful Swimathon challenge in to the increasingly popular open water environment.
