This years race was held last Saturday and it was fascinating reading the accounts of some of the runners.
John Kynaston has a great blog detailing is preparation for the race and it was good to read that he once again managed to complete the course in under 20 hours. I am not sure if it is a healthy pursuit, but it is some achievement!
There is another account of the race here.
I have walked bits of the route and could not imagine the endurance that these guys have to run it!
