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.

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 Triathlon - 2024

I would like to thank all the support staff for running the Ultimate Iron Man in Shropshire yesterday. It was the best event I have ever taken part in by a long way and although I could not complete the course I am glad I was fortunate enough to meet such nice people and take part in such a great event.  Keep up the brilliant work and I hope to see you again one day.  All the best.  Lester

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!

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 :)

Rachel

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.

Stratford Triathlon - 2024

The event was fantastically organised and helped create such a friendly, warm environment for all the competitors. The words of encouragement at every check point brought a smile to my face through some of the pain I was feeling. I thought it only right and fair that I reached out to you to compliment you and all the team for your hard work and support and I can’t wait for the next one.

Dean T

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.

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!

Joe

Warwickshire Triathlon - 2024

First time doing an official triathlon event having completed a 'do it yourself' event previously. What a great event, perfect for beginners to try Triathlon, if you are thinking about giving it a go take the plunge you'll love it! Well organised and a great event experience! Will be back for sure!
