George and I were discussing this a couple of Fridays ago with a thought to doing it again. Last year was a pretty horrible day but it is a fast course. It requires starting at silly o'clock to get there eg I was cycling to George's at 2.30am but I am sure it would be worth it on a good day.
Wondering if anbody else is interested. Jon did it last year aswell. Might be able to share transport if there is enough interest.
