We have a job to measure a 1-mile, basically straight (out/back) course, in a park, that will be used for a marathon and for a half marathon. What's the best way to establish the turnarounds; PK Nail at each end 5280-ft apart, or a 10-ft diameter turnaround at each end? If the latter, should we measure 5260-ft with a 10-ft diameter at each end measured with a steel tape and marked for cone locations?
I remember a discussion on turnaround measuring by Pete Reigel, anyone have it?
