Henley Kids Fun Triathlon - 2024

I loved how friendly everyone was all through - all the supervising marshals and organisers were very helpful. In particular, I would like to call out Kerry for helping me sort out a helmet with my 6 year old running the triathlon (she borrowed it from her 7 year old son) and I couldn't have been more grateful. She was so incredibly helpful and inspiring. I hope she did her triathlon yesterday successfully :)

Ultimate Triathlon - 2023

I just wanted to say, what an event you guys put on! I really can't thank all the marshals and helpers enough for making the UK Ultimate the event the highlight of my triathlon career so far. The helpfulness and sheer enthusiasm of each and every person, who stood for hours in the hot sun handing out drinks and directing traffic really helped me to complete my first Iron distance event. I can still hear the cheers and shouts of encouragement now! If anyone deserves a medal, it's these guys. I really can't thank you all for an incredible event and I'll be back for certain! Cheers,

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.

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. 😀

Ultimate Triathlon - 2024

I would like to thank all the support staff for running the Ultimate Iron Man in Shropshire yesterday. It was the best event I have ever taken part in by a long way and although I could not complete the course I am glad I was fortunate enough to meet such nice people and take part in such a great event.  Keep up the brilliant work and I hope to see you again one day.  All the best.  Lester

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 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!

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!

Shropshire Triathlon - 2025

Brilliant Triathlon. Well run and really easy to navigate all aspects. Really nice laid back atmosphere. Big shout out to all the organisers and volunteers..👍

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.
