3.2.1 Courses must not contain any dangerous sections
3.2.2 Courses must be adequately marked throughout, such that complete strangers to the courses can follow without difficulty.
3.2.3 Courses must have less than 20% of the distance on asphalted road. Technically difficult sections and possible shortcuts must be manned by marshals.
3.2.4 Guidelines for downhill sections are as follows:
- They must not have rock steps
- They must not consist of loose rock terrain
- They must not exceed 30% rate of descent, averaged over each kilometre from the starting point of descent.
3.2.5 Any course which exceeds any parameter specified in rule 3.1 by more than 20% will not be accepted.
3.2.6 For mainly uphill courses, the total amount of descent should nor exceed 10% of the total ascent.
3.2.7 For up and downhill courses which do not start and finish at the same point, the difference between the total ascent and total descent should not be more than or less than 5% plus or minus.
