Can't do this in 2012 as injured with plantar fasciitis but did it for 1st time last year. Its a great race with a huge sense of history and occasion behind it - I killed myself with calf cramp to get under 4 hours but it was worth it. Don't listen to the miserable buggers who come along on the forum saying its a glorified trail race - its a classic and definitely one to do before you die.
