The difficulty of a route is representative of your perception and your personal assessment as a practitioner. To obtain an objective classification, Derupabike is based on a scale distinguishing the aptitudes related to the Physical condition and to the Technique of piloting.

The terms that define a level of difficulty represent the abilities of the practitioner. Personal aptitudes are defined as a range delimited by a maximum, a minimum or even an ideal average.


The classification is presented in 4 levels: from C1 to C4 for physical condition; from T1 to T4 for piloting technique.

Intermediate levels "+"

Example: T2 +.

The "+" annotation indicates that the skills corresponding to level (T3) must be applicable in all circumstances and under all conditions with ease. The skills required are approaching the next level.

The reasons for this addition can be various. Example; one or two sections technically more difficult than the level announced, compulsory passage or exposed, conditions depending on the season (cold, humidity), etc.

Aims of classification

The purpose of the classification is to help you correctly self-assess your level. This will allow you to better situate yourself and choose an offer that fully suits you.

Depending on your self-assessment and after making contact, we will be able to advise you on a suitable offer, or create a “tailor-made” itinerary that best meets your expectations and your abilities.
