RLSS UK is hosting the first open water swim to take place at a stunning reservoir set in the beautiful Sywell Country Park, Northamptonshire.

This is a brilliant opportunity for entrants (both adults and children) who are new to open water and who need support in their preparation and participation.

With a programme of activities provided by RLSS UK, Northamptonshire Sport (NSport), and Northants Triathlon (NTri) the aim is to introduce open water activities to the reservoir at Sywell Country Park, all delivered within a supportive atmosphere and an accredited framework that keeps participants safe.

Available activities:

  • 1600 Swim
  • 800m swim
  • 800m swim/5km run Aquathlon
  • Junior Swim/Run (various distances)

The Events and Prices

The Aquathlon combines two of the elements found in Triathlon (Swim and Run) leaving out the cycle section. Typically it’s an early season stepping stone for anyone wanting a challenge beyond swimming in open water and perhaps thinking about Triathlon. Like Triathlon, your time starts as you enter the water and only stops when you cross the finish after your run, so a quick transition from swimming to running is important if you want to record a fast time.
