Shropshire Triathlon - 2025

Shropshire triathlon was very well organised and welcoming for me as a first timer. Everything the participants needed was available and well explained. Lots of fun and lots of support.

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.

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 :)

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!

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.

Shropshire Triathlon - 2022

This is my 3rd year at Shropshire, opting to try the sprint distance to check out the alternate cycle route. An event I've loved everytime I've undertaken it. There is challenge with the hills, but we don't do triathlons for them to be easy. Great support from locals, spectators, crew and other competitors. Perfectly set up for serious competitors, first timers and those wanting to just push themselves. Will I be back, more than likely 😉

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.
