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!

Andrew Hudson

York Kids Fun Triathlon - 2024

Fantastic Day doing the York kids triathlon Really well organised especially as 500+ kids doing it!

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.

Rachel

Alderford Triathlon - 2024

The organisers were so helpful and friendly. Marshalls were so supportive and lovely. The lake was amazing. Course routes were well mapped out and pleasurable to ride/ run. I have already recommended this on Facebook to my club. I had an amazing time and would definitely come back. Thank you to all involved to make this happen. Also, as an aside- love the design of the medal.

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,

Ultimate Triathlon - 2022

Excellent organised event, feed stations were manned by brilliant marshals who were happy to chat and offer encouragement and I will be back 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!

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.

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!

Tina

Shropshire Triathlon - 2025

Thank you for yet another supremely run event. Always friendly but professional. It doesn’t matter what level you are, we are all treated the same. Great for beginners or seasoned athletes.
