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.

Caldicot Kids Triathlon - 2026

I just wanted to send an email of thanks for the Caldicott Kids Triathlon. My son, Wilfred and his friends from school all entered as team Berkeley Blasters to the tin event and none of them had ever done an event or competition before. The event was so brilliantly organised, right from initial race packs that made the children really feel like they were doing a 'big event' and getting suitably excited. They were all quite nervous about going into the pool without parents but were welcomed so well at the door, they were all beaming as they came out: so proud of themselves already. They picked up their parents en route to the bike and all seemed totally engaged in 'transition time'. They were all smiling so much doing the cycle and run and the fact they saw each other at different points of the event through the arena style route was really great for them: they talked about this lots afterwards. The big finish arch with a bell to ring and smooth transition onto a stage for a medal was a touch of genius: they all felt like they had won and had been treated fairly and celebrated equally. I've never felt more proud of a group of children: they all pushed themselves and confidence was so high afterwards. Allowing parents to transition with them allowed so much support and all I could see were proud parents everywhere. I must thank you as an organisational team for putting on such a brilliant day, encouraging children into sport and celebrating every single one of them. Wilfred couldn't believe that his name was called out on the loud speaker as he crossed the line: he honestly thinks he's famous now. As a group, the children raised £1370 for Childhood Tumour's Trust, a charity close to their hearts too. Thankyou again,

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.

Your events are the best in the country as is the way you treat your customers. You should all be applauded for such professional and high class service and care.

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.

Warwickshire Triathlon - 2024

First Triathlon. Awesome beginners event, pool system was effective, transition area had plenty of space, good fast bike route and the run was a mix of trail and path! Brilliant event, helpful staff and overall a good day!

Tina

Shropshire Triathlon - 2025

Thank you for yet another supremely run event. Always friendly but professional. It doesn’t matter what level you are, we are all treated the same. Great for beginners or seasoned athletes.

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.
