Lucky for me I've been training in Burghclere on the old disussed Railway track and in the woods and all, so I hope that the track wont be too different. I have this feeling that it will be like a cartoon with everyone rushing off the start line while I slow-mo away in a cloud of everyone's dust!!!
I've only been running since January, so I'm not hopeful of a good time, but hey, I guess it's the raising money that counts! (well, thats what I'll say anyways!) I never thought of going out to compton, I suppose because its a bit further away from me!
Good luck in your R4L !!
