Box End Swim Event – 1st August 2021

Box End Swim Event

Join us in the beautiful surroundings of Box End Watersports Centre for an Swim Event.

 Active Training World (ATW) will now offer swims at most of their triathlon events as part of the event programme. The new swims will take place in both lakes and sea and will vary in distances from 750m up to 4.5km.

This Swim Event takes place alongside the days triathlon events and provides the opportunity for a chip-timed swim race in the crystal-blue water of Box End Lake, over your choice of distances varying from 750m up to 3km.

As a friendly swim event it is open to everyone, regardless of ability and, as with all our swims, water safety will be on hand to ensure you have a safe and enjoyable experience.

We also know that not everyone is a fan of a mass swim start so our starts are flexible. Depending on COVID restrictions starts will be in a time trial format where you will start 1 by 1, in 20 second intervals, with the fastest predicted swim times being set off first. Or in small waves, allowing you to experience the thrill of a smaller mass start, BUT with the option of being started off behind the field, like in our time-trial stats, so you have a clear run and the best chance of your personal best!

After the event, the Box End site includes a restaurant and bar (www.boxendpark.com) and for those wishing to round off great day or weekend away in the local countryside, there is camping available on site (subject to Covid restrictions).

Many people are understandably nervous regarding entering events again and we want to assure you that we take every measure we can to organise a safe, socially distanced event. To see this in action watch our video Covid-19 Safety at ActiveTrainingWorld Running and Triathlon Events.
