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

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.

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!

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!

Ultimate Half Triathlon - 2022

I love this event, maybe I'm biased as this is my training lake, even so it is fantastically well organised great friendly atmosphere and a course good for beginners and a PB. I've done the Full twice and the Half 3 times. I'll do it again.

Henley Triathlon - 2024

This is a favourite of mine as it was my first Tri five years ago. Really friendly but ran like clockwork.

Jo

York Triathlon - 2023

Shropshire Triathlon - 2025

Did the ellesmere middle distance. Really professionally run competition. Marshalls and support staff were great and the whole event ran very smoothly. Would definitely attend an event again

Tina B

Alderford Triathlon - 2022

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

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
