THE INTERNATIONAL SKI COMPETITION RULES (ICR) BOOK II - Fis

Rhythm should not be broken by too many sharp changes in direction or
steep climbs. The downhill sections must be laid out so that they create a
challenge to the competitors. At the same time it should be possible to ski
the course even under fast conditions.
311.1.2 In principle, the Cross-Country course should consist of
- One third uphills defined as climbs with a gradient between 9% (1:11)
and 18% (1:5.5) with height differences over 10 meters plus some
short climbs steeper than 18%.
- One third undulating, rolling terrain, utilizing all terrain features with
short climbs and downhills (with height differences of 1-9 meters).
- One third varied downhills, demanding versatile downhill techniques.
311.1.3 At OWG, WSC, JWSC, WC and COC Cross-Country competitions the
courses may only be used in the direction established in the homologation
certificates.
311.1.4 A ski glide testing area with testing tracks for all participating teams must
be located close to the stadium. It should be close to the team wax cabins
and warm-up track. The testing tracks must be prepared to the same
standard as the competition tracks.
311.1.5 Warm up courses should be prepared as close as possible to the stadium.
311.2 The Homologation
311.2.1 All FIS Cross-Country competitions should be carried out on homologated
courses. The details on homologation procedure are described in FIS
Cross-Country homologation manual.
311.2.2 In competitions designed for Cross-Country sport promotion it is possible
to use courses outside of the homologation standards providing they have
been approved by the Sub-Committee for Rules and Control.
311.2.3 The Organiser must supply copies of the approved course maps and the
homologation certificate to its TD. A graduated scale and a north direction
arrow must be included.
311.2.4 Definitions
311.2.4.1 HD (height difference) is the difference in height between the lowest and
highest points of a competition course.
311.2.4.2 MC (Maximum climb) is the climb with the highest partial height difference,
in other terms, the biggest uphill. The uphill can be interrupted by a section
of undulating terrain that does not exceed 200 m in length or a downhill
that does not exceed 10 m PHD.
311.2.4.3 TC (Total climb) represents a total of all climbs on the course.
