What an amazing experience!! This was my first ever run event and I absolutely loved it. The whole event was so well managed, the route was fantastic and the Marshalls were great and supported us as we made our way around. I also loved how the lady at the finish line also gave us a shout as we finished. Thoroughly enjoyable and would recommend this to anyone!! Thank you ATW, I definitely have the race bug 🙌🏻
