There is a designated car park and you will need to walk a short distance with all your equipment to the front of the school building (200m). 


Every child will receive a finishers medal once they cross the finish line. Presentations will take place as soon as possible after each age group has finished and will be awarded 1st to 10th place (Youth will be 1st – 5th).



These will go on Kronos: sport (https://events.kronosports.uk/results) as soon as possible after the event.


Expo Area

There will be an Expo and Refreshments stands and a variety of stalls.



We politely request no dogs on the school grounds, please.


Child Protection & Safety

Throughout this event, the safety and well-being of the children competing in the event are of paramount importance to us, but also to the continued success of children’s triathlon in the United Kingdom. The race marshals are there to ensure the safety of the children at all times throughout the race. Certain key officials for the triathlon have been vetted by the CRB or DBS and British Triathlon to work with children.

We look forward to seeing you on race day.
