Thanks Trig - I seemed to recall there were some slight deviations on actual race day but the recce map (obviousy!) gives a good clue as to the rest of the route. I doubt I'll be leading at any point so there's usually a body or two in sight to give me a general clue as to whether I'm going in the right direction. I'm already 'looking foward' to those lung busting climbs - especially the 500 feet ascent in the last mile. You are a cruel man!
