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 

Kevin Vince

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.

St Thomas' School

Cheshire Kids Fun Duathlon - 2024

I just wanted to say a huge thank you from us at St Thomas', the children and parents had an absolutely amazing day. The feedback from parents has been phenomenal in terms of seeing their children achieve something they never would have normally attempted, also the children have still been buzzing and talking about it (even wearing their medals in school today). It most certainly was an experience they will never forget.

Lester Watt

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

Rachel

Alderford Triathlon - 2024

The organisers were so helpful and friendly. Marshalls were so supportive and lovely. The lake was amazing. Course routes were well mapped out and pleasurable to ride/ run. I have already recommended this on Facebook to my club. I had an amazing time and would definitely come back. Thank you to all involved to make this happen. Also, as an aside- love the design of the medal.

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!

Alex M

Alderford Triathlon - 2022

Best triathlon I’ve done. Did the Olympic distance. Well organised, water was the best open water I’ve seen, genuinely almost sweet tasting water.

Sean Kachmarski

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.
