This is too big to hide away in a thread like this. I take my hat off to you. Which way did you do it, clockwise or anti? Who were you running with at the time? Were any of my ClM runners on it that time? I could ask you questions about this forever.
Clockwise. Me and my mate Alan Deacon (1030) did it together. I think we started at about 5pm so the night section must have been somewhere between Helvellyn and Bowfell. We used to train down in Sussex by running up and down the Downs which was inadequate but all we have in the way of hills. A couple of trips up to reccie the sections. On one of these we met and became friends with the great Eric Draper who helped us immensely with training tips and 'witnesses'. Some friends came up to support and witness too. We knew it was in the bag when we got to Robinson and, much to Alan's disgust, I virtually walked in to Keswick and deprived him of a sub 23. I didn't care though, sub24 was fine by me. I drank a glass of bubbly at the Moot Hall and puked it up!
To be honest, and I'm not being modest, you or any decent runner could do it with the right training. I think your marathon PB (and 10KM?) is better than mine. I was 43 when I did it so age isn't necessarily a barrier.
CIM?
Incidentally Eric Draper had done a back to back double in 50 hours missing out on the 48hrs he wanted. That
was a great effort.
