I just want to say a big thank you to all the volunteers in today event they were fantastic. In particular a big thank you to the man who was in the lake looking after those swimmers who weren’t so confident and reassuring them. It really was fantastic and we will definitely be back next year. It was all you could want from a kids event and more.



Dear UK Triathlon team

I just wanted to say a huge thank from us at St Thomas', the children and parents had an absolutely amazing day at the Cheshire Duathlon.  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.

This was a big investment for our school, so from a personal point of view, the event was extremely well organised both prior to and on the day. The UK Tri team made us feel really special throughout the day taking their time to do extra photos and make special announcements etc, this meant a lot to both myself and the children. I can genuinely say that Saturday will be one of my career highlights forever.

The children and myself wanted to send you all a picture of us with our medals to say a big thank you for creating the most amazing memories and giving us the most magnificent sense of achievement.

If I can be of any help in terms in speaking to other schools etc just let me know.

Many Thanks

Louise and Team St Thomas'
