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.

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 :)

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!

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.

Stratford Triathlon - 2024

Granted this was our first Triathlon Relay event, so our experience is very limited. However, we felt that the Stratford Triathlon was very well organised. We were kept updated via emails as the event approached, and thought the day went smoothly. Every member of the staff at the event was very kind, helpful and encouraging. Everything was explained very clearly at briefing, and the registration process was smooth and reassuring. The facilities were fit for purpose and the cycle and running routes were well marked. We had a great day. Sincere thanks to everyone involved.

Henley Triathlon - 2024

This is an outstanding beginner triathlon - a pool swim, then an undulating bike course (2 laps) and 4 laps of the playing field for the 5km run. It is a split transition so you need to be quite planned and organised, but the support is excellent and the finish area is really good. Definitely bring the family along and have a great day!

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.

Garry

York Triathlon - 2023

This was my 4th time at York triathlon. Great signage to car park, registration, transition and to the pool. Everybody was friendly and helpful. Very compact venue through both transitions, and closed roads on the laps on the bike and run were very welcome. Nice to have age groups go up in every 5 years with prize and goody bag, so many venues go in 10 years up to vet 50s only. Only one negative point, Ha ha, my run was rubbish! Hopefully be there next year.

Joshua

Warwickshire Triathlon - 2024

First Triathlon. Awesome beginners event, pool system was effective, transition area had plenty of space, good fast bike route and the run was a mix of trail and path! Brilliant event, helpful staff and overall a good day!

Melanie M

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.
