384.4.4 Classical Technique
Normally the course should be set with two tracks. Where the width makes
it possible, more tracks should be set. In curves the tracks should only be
set if the skis can glide unrestrained in the set track. Where the curves are
too sharp or the speed is too high to remain in the tracks, then the tracks
should be removed. In steep downhills or other locations as designated by
the TD and chief of competition, no tracks should be set. In the finish area,
the last 200 meters should be set with as many tracks as possible. In appropriate
situations, with approval of the TD and the chief of competition,
course grooming may take place during the competition.
384.4.5 Both Techniques
Competitions may be carried out in both techniques at the same time and
on the same course. In such cases, the course for free technique should
be separated from the classical course with appropriate barriers or markings
so classical competitors do not have the opportunity to use the other
course and vice versa. Each course should be packed and prepared in
accordance with article 384.4.3 and 384.4.4.
384.5 Measuring and Marking
384.5.1 The competition course must be measured for length from start to finish by
chain, tape or measuring wheel. Each kilometer should be marked. The
last 500 meters and the last 200 m should also be marked. Places such as
steep downhills, curves, crossings should be given special marking.
384.6 Feeding
384.6.1 Feeding stations should be provided approximately every 10 km. If the
course is difficult, the distance between the feeding stations may be shortened.
In easy terrain, the distance may be increased. For competitions
longer than 50 km different types of drinks and other appropriate nourishment
should be provided.
384.6.2 When team officials give refreshments to their competitors, they must follow
ICR 344.2.
384.7 Course Layout
384.7.1 PCCC should be conducted to accommodate all levels of competitors from
recreational racers to elite athletes. Course layout should be adapted to
the skill levels of the participants.
384.8 Bonus sprints
384.8.1 When having sprints along the course, the final approach to the sprint
should be at least 75 m straight that is wide enough for 2 competitors to
sprint side by side. The bonus sprint finish line must be clearly marked.
Sprint controllers must be assigned to each bonus sprint.
385 Control
