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.

Elizabeth Atkinson

Ultimate Half Triathlon - 2024

I just want to say what a super, super, super well run event it was yesterday. So well organised, really lovely routes and everyone was so friendly. My first proper Tri and I loved it! Huge thank you to all involved. Elizabeth

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.

This event will will change your life - go on and get out there and have a go !!!! Thanks team

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.

Emma Barlow

Shropshire Triathlon - 2025

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.

Sarah

Alderford Kids Fun Triathlon - 2024

I just want to say a big thank you to all the volunteers in today event they were fantastic. In particular a big thank you to the man who was in the lake looking after those swimmers who weren’t so confident and reassuring them. It really was fantastic and we will definitely be back next year. It was all you could want from a kids event and more.

Garry

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.

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.
