Alton Water:

The Great East SwimRun takes place in and around the picturesque Alton Water reservoir near Ipswich, Suffolk. The reservoir provides the main source of drinking water for Ipswich and the southern part of Suffolk.

Alton Water offers the opportunity to do far more than swim – it’s the perfect location for walks, cycle rides, wildlife spotting and family picnics. With miles of unspoilt countryside, numerous award winning beaches and scores of enchanting towns and villages within reach of Alton Water, Suffolk makes an ideal choice for a short break. Only an hour’s train journey away from London Liverpool Street station.

The event starts and finishes at the main Great East Swim event site and the 4 swim courses in Alton Water include the start and finish sections of the Great Swims.

Run 1: Quick and flat through grassland and light woodland. The course is predominantly based on hard packed surface with some softer areas under trees.

Run 2: Undulating, sweeping run on a variety of surfaces, includes three steep descents and several short, sharp climbs.

Run 3: Gently undulating course based largely on packed sand cycle track and path which follows the contours of the reservoir with the water regularly visible.

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
