Two track measuring

If the surface is not consistent with your calibration course, then set up a cal course on that surface.

Next, follow are method for certifying.

Gene, I passed along your suggestion to the measurer.

I want to go on record as being opposed to measuring any non-paved surfaces that represent more than 10% of a race distance. We get into the 'integrity' of those off-road surfaces - rocks, sand, dips, loose soil, etc which can seriously compromise how accurate we are. I simply don't feel confident I'm measuring accurately on those surfaces. I recognize our method will still likely yield better measurement than pretty much any other method - but I still feel uneasy about soft surfaces.

Scott - if you set up a calibration course (I do 300-foot one-off cal courses for this), and use your non-paved calibration numbers for that portion of the course, you should have a very good measurement. If you only use your paved cal course numbers, your course will be long.

No problem with mixed-surface courses, as long as calibrations are done for both surfaces.
