The Event

The Henley UK Kids Fun Triathlon is now in its 11th year and held within the grounds of Henley Leisure Centre & Gillotts School, located just outside the pretty riverside market town on the River Thames.

The Kids event has been over-subscribed for the last few years resulting in entries closing early, so be sure to avoid disappointment and book early.

  • Indoor pool swim
  • Grass cycle & run course on Gillotts School playing fields

As organisers of the biggest triathlon series across the UK we are passionate and proud about what we do.

The Kids Fun Triathlons are no exception and leave everyone with a special sense of achievement at the end of an event when hundreds of smiling kids faces, parents words of appreciation and promises to return next year confirm that the end result was worth every bit of hard work all round.

NB: There will be a promotional video being filmed and photographs being taken at the event so please be aware of this.

Please Note: Competitor Race Day Information (Individual Start Times, Bib Numbers etc) will be emailed out to competitors 7-10 days before the event.

Henley Kids Event- Main Course

The pool is 25 metres long, tumble turns are not allowed.

Children will be started at 20 second intervals in the pool. The swim course is very straight forward and there will be a verbal briefing prior to each child starting.

A swim cap will be given to each child and must be worn. Children may use their own swim cap instead if preferred.

The cycle course is fairly flat and on grass.

The course is completely post and taped making it clear to follow and is entirely within the school grounds.

Children will not be allowed to take part without a bike helmet.

The run is fairly flat and entirely on grass. The course is again completely post & taped and within the grounds of the school.

  • The whole of the bike & run course will be post and taped, making it very easy to navigate for the children.
  • Parents/guardians, if you have a wristband, you are allowed into the cycle transition areas with your children to help them.
  • The whole of the bike & run course is on hard compact grass, as well as being inside the school grounds, making it safe for the children.


Thanks for the kids event on Saturday. Our 7 year old was thrilled to be able to do her first triathlon and thoroughly enjoyed it. Our 9 year old had a slight wobble at the start being amongst all the bigger boys and girls in the gold triathlon but was really pleased to have done it in the end and loved having a longer run distance as that’s his favourite discipline.

Jasper loves a competitive event but I think it’s so important that these sort of events also exist to encourage kids into the sport. I overheard one lady say that her daughter had never done anything like this before and she was going to look into joining a Tri club. And the girl was of an age when so many of them give up sport. I would say that makes the day successful!!


Thank you for a great weekend. My daughter enjoyed her first triathlon and I had a fantastic day yesterday! Many thanks

Testimonial from a Headteacher

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 at the Cheshire Duathlon.  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'
