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.

I started off competing in shorter triathlons with UK Triathlon. I have since competed in 9 full distance races, all of the other full distances being with an alternative well known global brand. The UK Ultimate was a breath of fresh air. An absolute bargain compared to the previous full distance races, but the main highlight was that it was such a nice event. The location was lovely, everything went so smoothly and the nutrition available at each feed station was excellent.

Mainly I will forever remember just how friendly everyone was. Every person helping out at each feed station were so friendly despite being out there all day. The competitors were friendly and the people that had come along to support were also just amazing. 

It was also really nice after previous full distance triathlons being so strict on the run rules in particular, that on this event family and friends weren't discouraged from supporting athletes.

I had a really magical day. 

Thank you so much.

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!

I've just completed the 2018 Ultimate. What a fantastic event from start to finish. The things I loved about today's event would be far too long to list here. But I would like to make a special mention for the marshals. They can make or break and event and today they were exceptional.

For anyone thinking of doing a triathlon, this is the one. Stunning location, great course, excellent organisation, the best marshals in the business. Everything to love.
