For a world record to be considered as such by the IAAF, the marathon course must have 42.195 km measured using the ‘calibrated bicycle method’, which consists in fitting a Jones Counter (see post’s image) between the left fork leg and the front wheel of a bicycle which counts the revolutions of the wheel and ridding such bike through the course, after several fine tuning and calibration, in order to properly measure it.
The other criteria impose that:
a) a course’s start and finish points measured along a theoretical straight line between them shall not be further apart than 50% of the race distance.
b) The decrease in elevation between the start and finish shall not exceed an average one meter per km.
The list of certified Marathons that meet these criteria, as since last May 1st 2013, as well as the Russia’s 2013 World Championships Marathon Course can be checked on:
