Henley Triathlon - 2024

This is my second Triathlon and yet again had a super race. A big thankyou to all who put so much work into running these events. I have found everyone very helpful,and last week phoned uk triathlon with a couple of questions and yet again my mind was put at rest. So don't hesitate enter Henley next year and have a great time.

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

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.

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.

Birmingham Triathlon - 2024

It was my first open-water triathlon and thought the organisation was brilliant. A big thank you to all the organisers and volunteers. The signs were just right, the marshall in place, the helping hands in and out of the water, the smiling faces and race day support, all of you were big stars, thanks.

This was my first Tri and I'm so pleased I chose this event, the organisers and marshals were endlessly friendly and supportive and had all the answers! All other athletes were friendly, kind and so motivating!

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.
