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!

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.

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

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.

Caldicot Kids Triathlon - 2026

I just wanted to send an email of thanks for the Caldicott Kids Triathlon. My son, Wilfred and his friends from school all entered as team Berkeley Blasters to the tin event and none of them had ever done an event or competition before. The event was so brilliantly organised, right from initial race packs that made the children really feel like they were doing a 'big event' and getting suitably excited. They were all quite nervous about going into the pool without parents but were welcomed so well at the door, they were all beaming as they came out: so proud of themselves already. They picked up their parents en route to the bike and all seemed totally engaged in 'transition time'. They were all smiling so much doing the cycle and run and the fact they saw each other at different points of the event through the arena style route was really great for them: they talked about this lots afterwards. The big finish arch with a bell to ring and smooth transition onto a stage for a medal was a touch of genius: they all felt like they had won and had been treated fairly and celebrated equally. I've never felt more proud of a group of children: they all pushed themselves and confidence was so high afterwards. Allowing parents to transition with them allowed so much support and all I could see were proud parents everywhere. I must thank you as an organisational team for putting on such a brilliant day, encouraging children into sport and celebrating every single one of them. Wilfred couldn't believe that his name was called out on the loud speaker as he crossed the line: he honestly thinks he's famous now. As a group, the children raised £1370 for Childhood Tumour's Trust, a charity close to their hearts too. Thankyou again,

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.

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.

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.

Cheshire Triathlon - 2021

This was the third time I have done this event and I'll be back again for the next one. I love this event as it's just really well organised and the whole setup is for getting people involved in triathlons. Great to see all the family members in the park and nice to see a load of different ages, abilities and states of triathlon addiction all racing together. The split transition makes your brain work on what to put where but if you read the race info then it's all set out. Well done to the team and volunteers.
