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

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

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

Lucy

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.

David P

North West Kids Fun Duathlon - 2024

Great event for all ages and abilities well marshalled and good briefings for all age groups. Ewan really enjoyed the whole event lots of smiles from him and other competitors

Mike J

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.

Eleanor Hobbs

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!

Ivan P

Ultimate Half Triathlon - 2022

Well-planned course with loads of feed and water stations. Especially liked the run which broke a challenging 13.1 miles down into 3 manageable laps. Highly recommended!

Jo Price

Alderford Kids Fun Triathlon - 2024

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

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.
