My guess would be that he didn't find it a total path as he was down there a couple of weeks before that, so might have actually taken him a couple of sessions!
Good work the man with scary biceps.
Coincidentally, Toru the Japanese beast was also down that way recently at the BMC meet. I think he was on pretty fine form, although nothing rediculous as far as I know. Some great photos on Alex Ekins's photo gallery if you want to check out some really inspiring pics of Cornish granite.
