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

What a great event, perfect for beginners to try Triathlon, if you are thinking about giving it a go take the plunge you'll love it! Well organised and a great event experience! Will be back for sure!

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

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.

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

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

Alderford Triathlon - 2022

This was my first Olympic triathlon and I loved it. Great course, well sign posted on cycle, marshals so supportive and very welcoming. Really enjoyed it and would recommend to others. Definitely do another one. Thanks

York Triathlon - 2024

Couldn’t have been organised any better I don’t think, had an amazing time, this was my first triathlon and I’m glad I chose this one as my first

Simon Clarke

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.
