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!

Shropshire Triathlon - 2025

Brilliant Triathlon. Well run and really easy to navigate all aspects. Really nice laid back atmosphere. Big shout out to all the organisers and volunteers..👍

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.

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 :)

Daniel

Ultimate Quarter Triathlon - 2024

This was a very well-organized event. Registration was seamless, and the other facilities were great. The lake swim was very pleasant. The bike course was fast and easy to navigate, with marshals at all junctions and good signage for the different races using the same roads. The out-and-back run was nice on a closed country lane, a little undulating but nothing too sharp that would sap the momentum from your tiring legs

Cheshire Triathlon - 2022

I love UK Tri events. Always extremely well organised and inclusive. This one is no exception. An open air brine pool, a flat bike course and a run in a park make it ideal for beginners. Equally the flat bike and run routes make it fast for those looking for a PB. The run route is 1.25k laps in a wide open park so spectators can cheer you to the finish all the way round. Be mindful that the pool is about 500m from the T2 and the finish, so T1 and T2 are in different places. Not to worry, your kit finds its way back to you. Overall a very relaxed introduction to either your first Tri or the new Tri season. Really enjoyed this one.

Ultimate Triathlon - 2024

I just wanted to say a huge thank you to everyone involved in the Ultimate last weekend. Everyone I came across that was involved with the day taking place were amazing. A special mention must go to those that were at the bike aid station half way around the lap, who once they were finished there, continued marshalling on the run route for the rest of the day. They had a longer day out there than I did.

Jude S

Birmingham Triathlon - 2024

This was my first and will definitely not be my last. Felt very well organised and carefully thought out. Course was well signed and the atmosphere from marshalls, competitors and spectators was brilliant. Sutton park is a beautiful venue.

Nick

Henley Triathlon - 2024

This is a favourite of mine as it was my first Tri five years ago. Really friendly but ran like clockwork.

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!
