Shropshire Triathlon - 2025

Did the ellesmere middle distance. Really professionally run competition. Marshalls and support staff were great and the whole event ran very smoothly. Would definitely attend an event again

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 😉

Henley Triathlon - 2024

This is my second Triathlon and yet again had a super race. A big thankyou to all who put so much work into running these events. I have found everyone very helpful,and last week phoned uk triathlon with a couple of questions and yet again my mind was put at rest. So don't hesitate enter Henley next year and have a great time.

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!

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.

Mel

Birmingham Triathlon - 2024

It was my first open-water triathlon and thought the organisation was brilliant. A big thank you to all the organisers and volunteers. The signs were just right, the marshall in place, the helping hands in and out of the water, the smiling faces and race day support, all of you were big stars, thanks.

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!

Your events are the best in the country as is the way you treat your customers. You should all be applauded for such professional and high class service and care.

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.

Alderford Triathlon - 2022

Best triathlon I’ve done. Did the Olympic distance. Well organised, water was the best open water I’ve seen, genuinely almost sweet tasting water.
