Open Water Swimming

Active Training World organise Open Water Swimming sessions at Merchant Taylors’ lake in Northwood. The lake is perfect for beginners and seasoned swimmers alike. There are 2 swimming loops in the stunning freshwater lake. One loop measures 750m and the other is shorter at 400m.

We have a full water safety crew on kayaks to support you in the water and an ATW staff member will be at the water edge to make sure everyone enters and exits the lake safely. 

Equipment Required

Wetsuits are not compulsory but a swim hat (preferably bright) is.


  • ActiveTrainingWorld want everyone to enjoy these open water swimming sessions safely and therefore we require everyone to adhere to our strict social distancing rules when attending the sessions. Anyone found to be flaunting the rules will be instantly banned from all future ATW open water swimming sessions.
  • Experienced Individual Sessions, Age Restrictions and Coaching Sessions
  • These open water swimming sessions are for individuals or family members only. You are not allowed to swim with a friend or a club mate unless they live in the same house as you.
  • We expect everyone attending these sessions to be a competent and confident swimmer but these sessions are not just for elite swimmers, speed in the water is not essential.
  • The sessions are now open to under 16’s who must also be confident swimmers. Under 16’s will only be allowed to complete the 400m lap. 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 100m loop on their first session. Once accredited in this way they will be allowed to swim the 400m lap on their own.
  • If you would like to be involved but are not an experienced swimmer then this is an excellent opportunity to book one of our coaching sessions with Aloha Tri! Please go to the booking site here
