Road race turn-around marks can vary widely depending on the width of the road, number of peak participants sharing the road and the race director’s ability to set it up. In contrast, measuring race-walk courses there is a necessary requirement to make turn-around points with nice wide radius turns. It does not hurt to document a road race turn-around like a race-walk, but often times a single nail in the center of the road works just fine. After the measurement, a race director can always set up a nice wide teardrop turn-around if he or she chooses to.
