Shropshire Triathlon - 2022

This is my 3rd year at Shropshire, opting to try the sprint distance to check out the alternate cycle route. An event I've loved everytime I've undertaken it. There is challenge with the hills, but we don't do triathlons for them to be easy. Great support from locals, spectators, crew and other competitors. Perfectly set up for serious competitors, first timers and those wanting to just push themselves. Will I be back, more than likely 😉

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.

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.

Zenobia M

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 :)

Tina B

Alderford Triathlon - 2022

This was my first Olympic triathlon and I loved it. Great course, well sign posted on cycle, marshals so supportive and very welcoming. Really enjoyed it and would recommend to others. Definitely do another one. Thanks

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!

Tina

Shropshire Triathlon - 2025

Thank you for yet another supremely run event. Always friendly but professional. It doesn’t matter what level you are, we are all treated the same. Great for beginners or seasoned athletes.

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.

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!
