It was excellent; I really enjoyed it. My family came too and had a great day also. I was really impressed how the event was organised - you guys seemed to have thought of everything. I've certainly got the bug and will now look at doing my first Olympic distance triathlon.... Going from no triathlon experience to a half iron distance was pushing it a bit! Please pass on my thanks to all your team for a fab day and their helping in getting me hooked! Kind regards Paul

Can't say thank you enough for the support of all the marshals and spectators today. Absolutely brilliant event with such an amazing atmosphere created by all those involved. 
The honking horn and the clappers were a great encouragement at the end/start of every lap!
Cheers guys! Duncan Senior
