I am doing the half marathon and it is anything but flat, the words 'killer' and 'made me sick' where some of the comments I have found from people doing the 10K, if you go onto runkeeper, there is a map of the route which shows the elevation also. But I am training for the Edinburgh Marathon in May so this is just what I was looking for and am really excited - although I don't think my legs will agree once finished. Hope you enjoy it and best of luck to everyone.
