I am a little disappointed that no one made any comments on my question #27 on the Application for Certification of a road course.
Jim how will you or did you answer question #27 when you measured the Sleepy Hollow Half Marathon course? I am thinking you will have to have 2 different calibration courses if the distances are about 50/50 (road/ trail). Or if it is 10/90 (road / trail) a calibration course just on the trail. Also it will probably be very hard to make a permanent calibration course on a trail so now you have to lay out a calibration course every time you measure a trail (is this maybe why no one has made any comments).
