Ah! Sorry Hustler, I should have remembered, you've been doing that for years, no? A friend of mine ran it in 2012 and I was one of his 2 main support crew, hard work that and no sleep for about 42 hours. He finished in 28 hours, about 8 longer than we were hoping for!
Would be good to see it on the Adventure Show, it's certainly a great event. Nice to think that folk were skiing a couple of thousand feet above as the race is in full flow.
