York Triathlon - 2024

Couldn’t have been organised any better I don’t think, had an amazing time, this was my first triathlon and I’m glad I chose this one as my first

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 :)

Daniel

Ultimate Quarter Triathlon - 2024

This was a very well-organized event. Registration was seamless, and the other facilities were great. The lake swim was very pleasant. The bike course was fast and easy to navigate, with marshals at all junctions and good signage for the different races using the same roads. The out-and-back run was nice on a closed country lane, a little undulating but nothing too sharp that would sap the momentum from your tiring legs

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!

North West Kids Fun Duathlon - 2024

This was our children's first Duathlon and they enjoyed it so much that they are already in training for the next meeting, we also enjoyed the day and atmosphere.

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!

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.

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.

Sarah

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.

Jude S

Birmingham Triathlon - 2024

This was my first and will definitely not be my last. Felt very well organised and carefully thought out. Course was well signed and the atmosphere from marshalls, competitors and spectators was brilliant. Sutton park is a beautiful venue.
