Hi Col,
The sprint was situated on the airfield approaching the access road, first left off the A10 on denny lane.
Its hard to say exactly where it was after going on site as i even struggled to find my way out after the event
The organisers mapped out a cone gate / coned track type mile long sprint track, which was much better than expected. i really enjoyed it, had a good, safe day
As for the surface I think the cones took you away from the very bad bits, but even so there were a couple of rutts and mudbaths (partially the bad weathers fault) to make it interesting! All the competitors cars looked like we'd been rallying rather than sprinting afterwards
