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.

Ultimate Half Triathlon - 2022

Well-planned course with loads of feed and water stations. Especially liked the run which broke a challenging 13.1 miles down into 3 manageable laps. Highly recommended!

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.

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

York Triathlon - 2023

This was my 4th time at York triathlon. Great signage to car park, registration, transition and to the pool. Everybody was friendly and helpful. Very compact venue through both transitions, and closed roads on the laps on the bike and run were very welcome. Nice to have age groups go up in every 5 years with prize and goody bag, so many venues go in 10 years up to vet 50s only. Only one negative point, Ha ha, my run was rubbish! Hopefully be there next year.

Alderford Triathlon - 2022

Great morning. My first recent triathlon( did one 13 years ago) so was extremely nervous!! But everything was simple and straight forward. Everyone was really helpful and extremely friendly! Thank you! Now which one to tri next. 😀

Ultimate Triathlon - 2023

I just wanted to say, what an event you guys put on! I really can't thank all the marshals and helpers enough for making the UK Ultimate the event the highlight of my triathlon career so far. The helpfulness and sheer enthusiasm of each and every person, who stood for hours in the hot sun handing out drinks and directing traffic really helped me to complete my first Iron distance event. I can still hear the cheers and shouts of encouragement now! If anyone deserves a medal, it's these guys. I really can't thank you all for an incredible event and I'll be back for certain! Cheers,

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

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.
