It is with sadness that we announce the Great East Swim will not take place in 2022 or in the future.  

The ambition was to bring a high quality open water swim event to Suffolk and we’ve thoroughly enjoyed seeing thousands of swimmers achieve their goals and raise significant funds for good causes.  

Unfortunately, the Great East Swim is not currently feasible in its current site in Alton Water, due to ongoing challenges with Blue-Green Algae which has caused the event to be impossible to stage in 2021. We have explored ways to mitigate this as well as looking for other locations, but unfortunately, we haven’t found a solution to the problem, and we can’t continue to operate without confidence the event will go ahead.  

We would like to say a heartfelt thank you to Suffolk County Council and Anglian Water for their excellent support, and of course, to everyone who has taken part or supported the event.  

Anyone who currently has an entry into the Great East Swim event will receive a full refund – all entrants will receive more details via email very shortly. 

Thank you for your understanding. 
The Great Swim Team 

How it works

For the Short distance single participants, as well as teams are permitted to take part.

SwimRun rules are simple - complete your chosen distance carrying everything you need from start to finish; this means wearing your trainers and wetsuit for both the land and water sections of the course.

Please note: There will be a mandatory briefing prior to the event (details tbc.)
