Superb event and well organised by ATW. Great course with wonderful support. As always a very well run event with a nice bit of bling at the end. Nathan

Great event. Mainly flat so great for a quick time. Also laps so never too far from transition / water stations etc. Great atmosphere and great support. Well organised. Lucy W

First ever Triathlon and really impressed. Lovely setting with a mostly flat course for running and cycling, the organisers and marshals were friendly, encouraging and helpful. Very well organised, kept you at ease whilst also motivated. May be my first but definitely won't be my last triathlon with them. Mark W

Perfect for a PB or first time. Really well organised and laid out to make transition really straightforward. Plenty of space for families or spectators with great views in a lush countryside setting. Highly recommend. Dan G

This is a great race. The lake is a lovely venue and I enjoyed the swim. The bike course is made for PBs, being flat and fast. The run is beautiful - it's around the edge if the lake on a gravel path. Ben R
