We have detailed below our most commonly asked questions. Please read through them to see if we have provided an answer to your question.

As we believe every swimmer should have a safe and enjoyable open water experience all of our venues go through a rigorous water-safety accreditation process put in place by RLSS and British Triathlon. Visit here to find out more.

Yes. You must be a confident swimmer able to swim 400m in a pool either in breaststroke or front crawl.

The sessions are open to under 16’s who must also be confident swimmers. Under 16’s will only be allowed to complete the 500m lap unless specific permission has been given by the lakeside staff.  Under 12’s must be accompanied at all times in the water by an adult from the same household. All swimmers between 12-16 yrs will be asked to do a monitored 150m loop on their first session. Once accredited in this way they will be allowed to swim the 500m lap on their own.

Swim distance will vary from 400m to 4.5km at our ActiveSwim events. At our open water swim venues, initially we will open 150m, 300m, and 500m laps. A 750m, 900m and 1.2km lap will be opened later in the season as the water and air temperature increase.
