Henley Kids Fun Triathlon 2025 - 2025

I hope you don’t mind me contacting you but I could not resist thanking everyone involved today at the Henley on Thames Kids Triathlon. What an amazing event and incredible experience for the children. My 5 year old competed and had the best time of his life. Every single member of staff we came across was helpful, supportive and genuinely cared about the event. It was definitely worth the ‘near’ 2 hour journey to get there, we will be returning again!

Warwickshire Triathlon - 2024

I just wanted to send a note of Thanks to the whole event team that covered the Warwickshire Tri today. It was my first event, and although there were some nerves, all the team were cheery, helpful and supportive making the day extremely enjoyable.

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 :)

Ultimate Half Triathlon - 2022

I love this event, maybe I'm biased as this is my training lake, even so it is fantastically well organised great friendly atmosphere and a course good for beginners and a PB. I've done the Full twice and the Half 3 times. I'll do it again.

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.

North West Kids Fun Duathlon - 2024

This was our children's first Duathlon and they enjoyed it so much that they are already in training for the next meeting, we also enjoyed the day and atmosphere.

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

Cheshire Triathlon - 2021

This was the third time I have done this event and I'll be back again for the next one. I love this event as it's just really well organised and the whole setup is for getting people involved in triathlons. Great to see all the family members in the park and nice to see a load of different ages, abilities and states of triathlon addiction all racing together. The split transition makes your brain work on what to put where but if you read the race info then it's all set out. Well done to the team and volunteers.

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.
