One of the things I always get concerned about in a case of incorrect course layout is that some runners assume it was bad course measurement. I measured a course for a race I subsequently ran where there was an official race mile marker sign misplaced by a quarter of a mile (short) on race day. The paint marking I had made during measurement was clearly visible on the pavement a quarter of a mile further on. I overheard talk between runners after the race questioning the validity of the course length as a result of this misplacement. I know that as a measurer this situation is typically outside of my control. However, whether a measurer likes it or not, there is sometimes association made between poor race management and the course measurement.
