Reply to "Certifying a course to be run on a track"

I don't think the approximate method shown above should be acceptable for certifying a course that will be run entirely on the track. It assumes circular curves. If you're going to assume circular curves you might as well just assume the track is 400 meters. And what are you going to do if the measurement comes out to 402 meters? Will you believe it? If you call it 400 in that case and it really is 402, then you'll be certifying a marathon that is 210 meters long.

Using a steel tape to measure a 100 meter cal course on the track and then using a calibrated wheel to measure the track twice probably doesn't take any more time than the 3 steel tapings of the approximate method.

I think the approximate method is ok when the track is just a small part of the course, but not when it is the entire course.
