Open Water Swimming Course

The event takes place on Saturday 17 June in Alton Water and is a great day out for swimmers, families and spectators. With farmers' markets, plenty of musical entertainment and swim distances ranging from a half mile right up to a 10k, there really is something for everyone!

We hope to see you at one of our open water swims in Suffolk next summer!



The Great East Swim course map is shown to the left including 1/2 mile, 1 mile, 2 mile, and 5k distances.

The Great East Swim 10k is also back by popular demand and will be 6 laps of the standard 1 mile course.


What will the course be?

The 10k course will consist of 6 laps of the Great Swim course. You will be constantly monitored by our safety team and have the opportunity to finish at the end of any lap should you need to on the day. Your time will stop when you go over the timing mat at the finish. 


If I don’t complete the 10k will I still get my finisher's pack?

Yes – lap counting is an honesty system and down to each individual swimmer. Regardless of when you come through the finish system you are still entitled to your finisher's pack.


Do I have to finish the Swim inside the 4 hour cut off time?

We will try and allow everyone to safely finish their swim. Due to the safety systems in place should people take longer than 4 hours we may have to ask them to finish a lap early, or have our safety teams bring them in. In addition to this we will be monitoring all swimmers and should our medical and safety team feel it is unsafe for any swimmer to continue at any point we may ask you to come in early. We will work with all swimmers to try and ensure they are able to finish the full 10k if it is safe to do so. Our priority is the well-being of swimmers.
