All the events are non competitive so every child will be a winner.

We still record an overall time for each participant and list them alphabetically so, if they wish, they can compare times after the event.

The distances and number of laps are indicated below. SC = Short Course LC = Long Course

What does safe environment mean?

The whole race takes place within the confined space of the event arena, meaning the children are on site at all times. They do not cycle on the roads or run outside of the venue, both the cycle and run courses are on grass (with the exception of York which uses the cycle track & velodrome) and are multi lapped so you can watch your child at all times.

What equipment is needed to take part in a triathlon?

  • Swimming costume or trunks
  • Bike
  • Helmet
  • Trainers
  • Swimming goggles (optional)

What equipment is needed to take part in a duathlon?

Dear UK Triathlon team

I just wanted to say a huge thank from us at St Thomas', the children and parents had an absolutely amazing day.  The feedback from parents has been phenomenal in terms of seeing their children achieve something they never would have normally attempted, also the children have still been buzzing and talking about it (even wearing their medals in school today). It most certainly was an experience they will never forget.

This was a big investment for our school, so from a personal point of view, the event was extremely well organised both prior to and on the day. The UK Tri team made us feel really special throughout the day taking their time to do extra photos and make special announcements etc, this meant a lot to both myself and the children. I can genuinely say that Saturday will be one of my career highlights forever.

The children and myself wanted to send you all a picture of us with our medals to say a big thank you for creating the most amazing memories and giving us the most magnificent sense of achievement.

If I can be of any help in terms in speaking to other schools etc just let me know.

Many Thanks

Louise and Team St Thomas'
