I've just signed myself up for it, and am now slightly bricking myself at the enormity of the challenge. The thought of being able to run that far! But I'm determined to do it. I'm running only up to about 7k on a good day at the minute so I have quite a lot to build up to! Anyone want to join me on this thread and give me tips on best ways to train? And anyone else planning to do it, please join this thread so we can support each other.
