Terms and Conditions for the Longest Swim on the Longest Day

The Longest Swim on the Longest Day is a  fundraising event for The Outdoor Swimming Society (OSS), run by OSS Trading, with 10% going to The Seagrass Project and 90% to The OSS (after costs).

The Outdoor Swimming Society is not able to assume legal responsibility to participants of The Longest Swim On The Longest Day. While we are always keen to share our passion for outdoor swimming, this is a virtual event with no safety cover and all swimmers must be solely responsible for making their own assessment as to the risks involved in any particular swim.

The Outdoor Swimming Society itself has no control or influence over the swims that swimmers choose to do as part of this virtual event, or on information shared on Facebook, using the OSS group or other groups, or the locations written about or featured in newsletters, the website.

The decision to participate in any swim must therefore be taken individually, and swimmers must not rely (in whole or in part) on views or information provided by The Outdoor Swimming Society and/or its members.  If you are in any doubt about the safety of a swim or your ability to complete it, you should not take part.

Swimming outdoors heightens the risk of serious injury or harm. The risks of outdoor swimming include (but are not limited to) hypothermia, drowning, sickness from polluted water, injury from wildlife, other swimmers, debris on the water, objects in the water (either visible or hidden beneath the surface) and diving or jumping into shallow water. The ‘safety’ of locations varies with the weather, the abilities and knowledge of the swimmer and over time – rainfall can dramatically change the safety profile of a swim spot. More information on understanding water is available in the ‘Survive’ section of this website.

To the maximum extent permitted by law, each of:

  • The Outdoor Swimming Society;
  • each individual acting on behalf of The Outdoor Swimming Society; and
  • any person involved in organising The Longest Swim on The Longest Day

exclude any liability for personal injury, death or other harm or loss to participants or to any other person or organisation as a result of their negligence.


By completing an entry into The Longest Swim on the Longest Day, you declare that you are capable of completing the swim(s) you have chosen to do as part of the event.

You understand that this is an unlifeguarded event and all swimmers swim at their own risk and you are solely responsible for keeping yourself safe.

You are also wholly responsible for any under 18s that you have signed up to the event, and it is recommended that in the water they have 1:1 adult supervision at all times.
