Unfortunately we've had to make the decision to put the 2020 Greewich Tritons Junior Aquathlon on hold as a result of the advice surrounding COVID-19.

If you've already entered, we'll refund you in full.


We may be able to run the event later in the year, or potentially combine it with the senior 'Clash of the Tritons' aquathlon if that's on - but we can't commit until we know more.

Until then, stay safe, stay fit and healthy and we look forward to hosting a great event as soon as we're able!


We are pleased to announce our 2020 children's only aquathlon on 31st May 2020.

The event will take place in the grounds of Colfe's School in Lee, south east London and is part of Triathlon England London Region's Junior Race Series.

Please note that you will need to be a member of Triathlon England on race day if you want your result to count in the Series.

Race pack, competitor information and day licences will be added to this page nearer the event date.


Race details

The race comprises a swim in the indoor 25m pool followed by a run on grass and tarmac paths around the school playing fields. There will be 5 race waves as follows:

  • Junior and Youth (15-19 years old): 400m swim / 4km run

Please be as accurate as possible with your predicted swim time as these are used to seed the starting order. You will get an opportunity to update this once entries close in May.



If you have to withdraw please notify us as soon as possible by sending an email to This email address is being protected from spambots. You need JavaScript enabled to view it. with RACE WITHDRAWAL in the subject line. We operate a refund policy that we think is fair for both you the athlete/parent and us the organisers:

  • If you withdraw more than 14 days prior to the event then you will get 50% of your entry fee back.
  • If you withdraw less than 14 days prior to the event then you will not get any refund. By this stage we will have committed to all the major items of expenditure. 

We reserve the right to pay refunds after the event has taken place.
