York Triathlon - 2023

Great day, great organisation, great participants, great crowds, thank you

Simon Clarke

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.

Alderford Triathlon - 2022

Great morning. My first recent triathlon( did one 13 years ago) so was extremely nervous!! But everything was simple and straight forward. Everyone was really helpful and extremely friendly! Thank you! Now which one to tri next. 😀

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.

St Thomas' School

Cheshire Kids Fun Duathlon - 2024

I just wanted to say a huge thank you 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.

Warwickshire Triathlon - 2024

This was my first Tri and I'm so pleased I chose this event, the organisers and marshals were endlessly friendly and supportive and had all the answers! All other athletes were friendly, kind and so motivating!

Lance Ball

Ultimate Triathlon - 2024

I just wanted to say a huge thank you to everyone involved in the Ultimate last weekend. Everyone I came across that was involved with the day taking place were amazing. A special mention must go to those that were at the bike aid station half way around the lap, who once they were finished there, continued marshalling on the run route for the rest of the day. They had a longer day out there than I did.

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.

Jen Z

Henley Triathlon - 2024

This is an outstanding beginner triathlon - a pool swim, then an undulating bike course (2 laps) and 4 laps of the playing field for the 5km run. It is a split transition so you need to be quite planned and organised, but the support is excellent and the finish area is really good. Definitely bring the family along and have a great day!
