Just to set your minds at rest, I have driven around this course today and as LF suggests there are one or two open spots, but the course could really be fast, there seems to be more downhills than up. It is through quite narrow country lanes, so hope there will not be much traffice on the roads as that would make it quite difficult.
It starts and finishes at the Beckingham Business Park at Tolleshunt Major and The Bell pub looks to be favourite for meeting up afterwards as this is very close to the finish.
