a theoretical straight line between them, shall not be
further apart than 50% of the race distance.
- The overall decrease in elevation between the start and
finish shall not exceed 1:1000, i.e. 1m per km (0.1%).
- Any course measurer who originally measured the course
or another “A” or “B” grade measurer in possession of the

course measured was the course run, normally by riding in
the lead vehicle.
