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.

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 - 2024

I loved how friendly everyone was all through - all the supervising marshals and organisers were very helpful. In particular, I would like to call out Kerry for helping me sort out a helmet with my 6 year old running the triathlon (she borrowed it from her 7 year old son) and I couldn't have been more grateful. She was so incredibly helpful and inspiring. I hope she did her triathlon yesterday successfully :)

Warwickshire Triathlon - 2024

This was my first triathlon and as soon as I arrived I felt completely at ease. Very well organised and lovely volunteers giving lots of encouragement. I’ve already signed up for next year. Would fully recommend, absolutely brilliant.

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.

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,

Joshua

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!

Lance Ball

Ultimate Triathlon - 2024

I just wanted to say a huge thank you to everyone involved in the Ultimate last weekend. Everyone I came across that was involved with the day taking place were amazing. A special mention must go to those that were at the bike aid station half way around the lap, who once they were finished there, continued marshalling on the run route for the rest of the day. They had a longer day out there than I did.
