There is a selection at the start of the registration process enabling you to "register for someone else under 18

Which strokes are permitted?

Front crawl and breaststroke are the only strokes permitted. You will be asked which stroke you are likely to use on registration. The waves you are allocated in may depend on the stroke that you select. Backstroke is not permitted due to safety reasons.

When do I find out my start time?

Start times will be communicated to participants on or around 10 October 2019. The start times may vary between 8am and 7pm and depend on the schedule of the event.

Can I choose my start time?

All start times are allocated (between 8am and 7pm) according to your estimated completion time that you submit on entering the event. You will be allocated a wave according to your swimming speed. It is only possible to choose your start time by paying the Wave Selection Fee in additional purchases. You can log in to your account and pay this, if you have not already done it and wish to select your wave. Please be aware that by electing a different wave, you are likely to be competing with swimmers of different abilities.

If you purchase the Wave Selection - this means you are able to choose the broad time of your wave start (i.e. before 10am, between 10.01am and 1.30pm and between 1.31pm and 6.30pm). The idea of this is to enable participants who are travelling long distances to be able to plan their travel ahead of time. There are a limited number of Wave Selections available, the reason for this is that the event does need to ensure the majority of swimmers in each wave are at the appropriate speed/standard for that wave. The Wave Selection option is one a first come, first served basis.

If I have purchased the Wave Selection - does that mean I can swim in any wave?

If you have purchased the Wave Selection - you can select the broad time that you will start. You will be placed in a wave that is for your distance. There are typically three waves throughout the day for each distance challenge.

If you are in a faster (most likely later) wave the cut off times are:

Marathon 10k (team and individual) - 5 hours

Are wetsuits or buoyancy shorts permitted?

No 😊 our event is pool-based, so we expect water temperature to be at levels not requiring wetsuits.
