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.

Ultimate Triathlon - 2024

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.

Alderford Triathlon - 2022

This was my first Olympic triathlon and I loved it. Great course, well sign posted on cycle, marshals so supportive and very welcoming. Really enjoyed it and would recommend to others. Definitely do another one. Thanks

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.

Alderford Kids Fun Triathlon - 2024

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.

Shropshire Triathlon - 2025

Did the ellesmere middle distance. Really professionally run competition. Marshalls and support staff were great and the whole event ran very smoothly. Would definitely attend an event again

Henley Triathlon - 2024

This is an outstanding beginner triathlon - a pool swim, then an undulating bike course (2 laps) and 4 laps of the playing field for the 5km run. It is a split transition so you need to be quite planned and organised, but the support is excellent and the finish area is really good. Definitely bring the family along and have a great day!

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 

Lester Watt

Ultimate Triathlon - 2024

I would like to thank all the support staff for running the Ultimate Iron Man in Shropshire yesterday. It was the best event I have ever taken part in by a long way and although I could not complete the course I am glad I was fortunate enough to meet such nice people and take part in such a great event.  Keep up the brilliant work and I hope to see you again one day.  All the best.  Lester
