It just might be the closest one in attendance. I do remember one race pausing because there weren't enough ambulances behind the peleton to make it safe. They were too busy dealing with previous crashes and it just became too dangerous to continue.
Just seen that GC time gaps will be taken at 3kms to go due to safety concerns of the finish. Just looked at it in google maps and its stupidly narrow and technical. I can see there are definitely better locations in Bury St Edmunds than that.
