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!

Rich Andrews

Stratford Triathlon 2025 - 2025

Thank you all so much for a fantastic event- I suffer extreme anxiety but everyone was so welcoming and helpful. Competing with a laryngectomy is very scary and today went like a dream - a massive thanks as well to all the marshals  Would recommend to everyone

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.

Mark L

Ultimate Half Triathlon - 2022

I love this event, maybe I'm biased as this is my training lake, even so it is fantastically well organised great friendly atmosphere and a course good for beginners and a PB. I've done the Full twice and the Half 3 times. I'll do it 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.

Henley Kids Fun Triathlon - 2022

They really did a great job of making the kids feel amazing. One of my kids was very reluctant, apprehensive, but afterwards, after finishing and hearing her name as she ran through the finish, she was asking what she can do next. Testament to the event. No expectation for the kids, just brilliantly organised fun and they want more.

Ultimate Triathlon - 2023

I just wanted to say, what an event you guys put on! I really can't thank all the marshals and helpers enough for making the UK Ultimate the event the highlight of my triathlon career so far. The helpfulness and sheer enthusiasm of each and every person, who stood for hours in the hot sun handing out drinks and directing traffic really helped me to complete my first Iron distance event. I can still hear the cheers and shouts of encouragement now! If anyone deserves a medal, it's these guys. I really can't thank you all for an incredible event and I'll be back for certain! Cheers,

St Thomas' School

Cheshire Kids Fun Duathlon - 2024

I just wanted to say a huge thank you from us at St Thomas', the children and parents had an absolutely amazing day. The feedback from parents has been phenomenal in terms of seeing their children achieve something they never would have normally attempted, also the children have still been buzzing and talking about it (even wearing their medals in school today). It most certainly was an experience they will never forget.

Elizabeth Atkinson
