I received an application from a race director who measured her own half and full marathons. She wants the two races to start in the same place, and in order to do that she had to make the half 15 meters longer than the standard distance. So far not a problem. But then she put a note at the bottom of the map that says "Official measured distance: 21.113km."
I'm not sure what to do. I can't really put 21.0975km as the distance on the certificate since it will disagree with the map. But I am concerned with the name of the race on the certificate being Whatever Half Marathon and then listing the distance on the certificate as 21.113km. Anyone who sees the certificate, and the map for that matter, will think the USATF doesn't know how long a half marathon is.
