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!

Shropshire Triathlon - 2021

A brilliant event with a brilliant atmosphere. Welcoming, fund and supportive, but great for those wanting a more competitive race too. Super friendly staff and very well organised. I'll definitely be back next year!

Warwickshire Triathlon - 2024

I just wanted to send a note of Thanks to the whole event team that covered the Warwickshire Tri today. It was my first event, and although there were some nerves, all the team were cheery, helpful and supportive making the day extremely enjoyable.

Alderford Kids Fun Triathlon - 2024

I just want to say a big thank you to all the volunteers in today event they were fantastic. In particular a big thank you to the man who was in the lake looking after those swimmers who weren’t so confident and reassuring them. It really was fantastic and we will definitely be back next year. It was all you could want from a kids event and more.

This was my first Olympic triathlon and I loved it. Great course, well sign posted on cycle, marshals so supportive and very welcoming. Really enjoyed it and would recommend to others. Definitely do another one. Thanks

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 - 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 :)

Fiona

A HUGE thank you and WELL DONE to all concerned for a wonderful event yesterday at Sutton Park - so well organised and everyone was really friendly and helpful - this was my 2nd tri and I loved it!!!

Cheshire Triathlon - 2022

This was my first triathlon and I was nervous but people on the phone beforehand were very reassuring and helpful. The marshalls on the day were lovely and supportive. A special shout out to the lady at the pool who helped me drag my teeshirt over my head! It was very well organised, overall it was a great day out and very enjoyable experience.
