Use of the Calibrated Bicycle Method is not hard-wired into the rules, but has been selected by RRTC as, without any doubt, the best currently available method for measuring a road running course.
The following rules pertain to the verification of road running courses when records are set. This may require re-measurement by an expert measurer before or after the race.
