Easy race to get to, quick parking and a speedy course :) Loved the atmosphere and great vibe at the finish line! Karina K
Another great event from the guys at ATW. Will definitely do this one again and recommend to everyone. It was the national champs but is suitable for all abilities. Very friendly. Pre race info was spot on and the course was easy to navigate. Marshalls were fantastic too. This years route was slightly different to last year and I think much better. Running along a dam is not something you get in many races! Nick C
Cannot rate this event highly enough. Was concerned as knew I would be one of the slower competitors but was told there was no cut off. I watched the last participant come in almost an hour after me and he was given as loud a cheer and as much support as the very first runner. We were supported all the way around by the amazing smiling and encouraging Marshals. The route was very clearly marked, the atmosphere was upbeat and friendly. Two opportunities to be cheered on the run and bike. Huge thank you to the organizing team for making this such a positive experience. And thank you for the absolutely fantastic free photographs! They are just amazing. Anne D
Well organised event. Plenty of signage and marshalls around course. Friendly and helpful marshalls for any questions you have and I had plenty. Great event for all abilities. This was my first duathlon and was never made to feel out of place. Will definately be doing it again and will look for other events organised by ATW. Jason B
