Henley Kids Fun Triathlon 2025 - 2025

I hope you don’t mind me contacting you but I could not resist thanking everyone involved today at the Henley on Thames Kids Triathlon. What an amazing event and incredible experience for the children. My 5 year old competed and had the best time of his life. Every single member of staff we came across was helpful, supportive and genuinely cared about the event. It was definitely worth the ‘near’ 2 hour journey to get there, we will be returning again!

Henley Kids Fun Triathlon - 2022

They really did a great job of making the kids feel amazing. One of my kids was very reluctant, apprehensive, but afterwards, after finishing and hearing her name as she ran through the finish, she was asking what she can do next. Testament to the event. No expectation for the kids, just brilliantly organised fun and they want more.

North West Kids Fun Duathlon - 2024

Great event for all ages and abilities well marshalled and good briefings for all age groups. Ewan really enjoyed the whole event lots of smiles from him and other competitors

Dean T

Ultimate Quarter Triathlon - 2022

Great atmosphere as usual, registration easy and helpful, marshals and staff always with a smile and a word of encouragment, also changed my event twice due to injury. Top guys, more flexible than some of the other event organisers. Would thoroughly recommend and will be back again.

Cheshire Triathlon - 2022

I love UK Tri events. Always extremely well organised and inclusive. This one is no exception. An open air brine pool, a flat bike course and a run in a park make it ideal for beginners. Equally the flat bike and run routes make it fast for those looking for a PB. The run route is 1.25k laps in a wide open park so spectators can cheer you to the finish all the way round. Be mindful that the pool is about 500m from the T2 and the finish, so T1 and T2 are in different places. Not to worry, your kit finds its way back to you. Overall a very relaxed introduction to either your first Tri or the new Tri season. Really enjoyed this one.

Ultimate Half Triathlon - 2024

I just want to say what a super, super, super well run event it was yesterday. So well organised, really lovely routes and everyone was so friendly. My first proper Tri and I loved it! Huge thank you to all involved. Elizabeth

Stratford Triathlon - 2024

Granted this was our first Triathlon Relay event, so our experience is very limited. However, we felt that the Stratford Triathlon was very well organised. We were kept updated via emails as the event approached, and thought the day went smoothly. Every member of the staff at the event was very kind, helpful and encouraging. Everything was explained very clearly at briefing, and the registration process was smooth and reassuring. The facilities were fit for purpose and the cycle and running routes were well marked. We had a great day. Sincere thanks to everyone involved.

Caldicot Kids Triathlon - 2026

I just wanted to send an email of thanks for the Caldicott Kids Triathlon. My son, Wilfred and his friends from school all entered as team Berkeley Blasters to the tin event and none of them had ever done an event or competition before. The event was so brilliantly organised, right from initial race packs that made the children really feel like they were doing a 'big event' and getting suitably excited. They were all quite nervous about going into the pool without parents but were welcomed so well at the door, they were all beaming as they came out: so proud of themselves already. They picked up their parents en route to the bike and all seemed totally engaged in 'transition time'. They were all smiling so much doing the cycle and run and the fact they saw each other at different points of the event through the arena style route was really great for them: they talked about this lots afterwards. The big finish arch with a bell to ring and smooth transition onto a stage for a medal was a touch of genius: they all felt like they had won and had been treated fairly and celebrated equally. I've never felt more proud of a group of children: they all pushed themselves and confidence was so high afterwards. Allowing parents to transition with them allowed so much support and all I could see were proud parents everywhere. I must thank you as an organisational team for putting on such a brilliant day, encouraging children into sport and celebrating every single one of them. Wilfred couldn't believe that his name was called out on the loud speaker as he crossed the line: he honestly thinks he's famous now. As a group, the children raised £1370 for Childhood Tumour's Trust, a charity close to their hearts too. Thankyou again,

Lucy

Warwickshire Triathlon - 2024

This was my first triathlon and as soon as I arrived I felt completely at ease. Very well organised and lovely volunteers giving lots of encouragement. I’ve already signed up for next year. Would fully recommend, absolutely brilliant.
