An excellent experience from start to finish. The route was brilliantly marked out, the food was gorgeous and plentiful, the staff couldn’t have been more helpful and supportive if they tried, a wonderful event that I can’t praise highly enough.
An amazing event, extremely well organised with fantastic, enthusiastic staff. So much support, food, drink and tonnes of information available if you ever had any questions. I’ve done lots of different races and this ranks as one of the best. It was tough but so worth it...a little bit sad it’s over.
