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

Ultimate Triathlon - 2024

I just wanted to say a huge thank you to everyone involved in the Ultimate last weekend. Everyone I came across that was involved with the day taking place were amazing. A special mention must go to those that were at the bike aid station half way around the lap, who once they were finished there, continued marshalling on the run route for the rest of the day. They had a longer day out there than I did.

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.

Stratford Triathlon - 2024

Granted this was our first Triathlon Relay event, so our experience is very limited. However, we felt that the Stratford Triathlon was very well organised. We were kept updated via emails as the event approached, and thought the day went smoothly. Every member of the staff at the event was very kind, helpful and encouraging. Everything was explained very clearly at briefing, and the registration process was smooth and reassuring. The facilities were fit for purpose and the cycle and running routes were well marked. We had a great day. Sincere thanks to everyone involved.

Henley Triathlon - 2024

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

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.

Barnaby C

Henley Kids Fun Triathlon - 2022

They really did a great job of making the kids feel amazing. One of my kids was very reluctant, apprehensive, but afterwards, after finishing and hearing her name as she ran through the finish, she was asking what she can do next. Testament to the event. No expectation for the kids, just brilliantly organised fun and they want more.

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.

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.

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
