I was in Thetford today - well I live here so that is no surprise. Saw a bloke on a road bike with drop handlebars doing the red route including the Beast of England. Well impressed. Saw him afterwards too and he had a flash road type bike with 1.5 inch tyres and hydraulic disks - looked impressive and expensive! Thetford is not difficult but the Beast takes no prisoners.
