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 :)

Neil Dallywater

Ultimate Triathlon - 2023

I just wanted to say, what an event you guys put on! I really can't thank all the marshals and helpers enough for making the UK Ultimate the event the highlight of my triathlon career so far. The helpfulness and sheer enthusiasm of each and every person, who stood for hours in the hot sun handing out drinks and directing traffic really helped me to complete my first Iron distance event. I can still hear the cheers and shouts of encouragement now! If anyone deserves a medal, it's these guys. I really can't thank you all for an incredible event and I'll be back for certain! Cheers,

Cheshire Triathlon - 2022

This was my first triathlon and I was nervous but people on the phone beforehand were very reassuring and helpful. The marshalls on the day were lovely and supportive. A special shout out to the lady at the pool who helped me drag my teeshirt over my head! It was very well organised, overall it was a great day out and very enjoyable experience.

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

Kieran

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

Kerry T

Ultimate Triathlon - 2022

Excellent organised event, feed stations were manned by brilliant marshals who were happy to chat and offer encouragement and I will be back next year

Jo Price

Alderford Kids Fun Triathlon - 2024

Thank you for a wonderfully organised event. My daughter had a wonderful time once again. Well done

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.

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.

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.
