Stratford Triathlon 2025 - 2025

Thank you all so much for a fantastic event- I suffer extreme anxiety but everyone was so welcoming and helpful. Competing with a laryngectomy is very scary and today went like a dream - a massive thanks as well to all the marshals  Would recommend to everyone

Stratford Triathlon - 2024

I was unsure what to expect as 2024 Stratford Triathlon was my First Triathlon and my first with UKTriathlon. All I have is 2 words ABSOLUTELY BRILLIANT! All people friendly, helpful and supportive. VERY WELL organized. I am so glad, as I have entered 5 other UKTriathlon Events this year. I am so looking forward to them. Well done and my heartfelt thanks to the entire team who made me feel so welcome.

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.

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.

Stratford Triathlon - 2024

The event was fantastically organised and helped create such a friendly, warm environment for all the competitors. The words of encouragement at every check point brought a smile to my face through some of the pain I was feeling. I thought it only right and fair that I reached out to you to compliment you and all the team for your hard work and support and I can’t wait for the next one.

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!

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

Cheshire Triathlon - 2022

I love UK Tri events. Always extremely well organised and inclusive. This one is no exception. An open air brine pool, a flat bike course and a run in a park make it ideal for beginners. Equally the flat bike and run routes make it fast for those looking for a PB. The run route is 1.25k laps in a wide open park so spectators can cheer you to the finish all the way round. Be mindful that the pool is about 500m from the T2 and the finish, so T1 and T2 are in different places. Not to worry, your kit finds its way back to you. Overall a very relaxed introduction to either your first Tri or the new Tri season. Really enjoyed this one.

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!
