"We had 366 on our first day and this weekend we weren't that far off double that.
"It really is quite amazing how it has grown. People have said it's just "a run round the park" but it really is so very much more than that. It has encouraged people from all walks of life to run, jog or walk and the friendships that have been made show we really have a warm and welcoming community spirit here."
