What makes a cross-country course?
Officials' detail · During the race · 1 of 1Courses must be homologated and should be about one third climbs, one third rolling terrain and one third descents. Climbing limits are set for each lap length. Races start and finish in a stadium with a 50 m start zone, a finish zone of at least 50 m and, for team races, an exchange zone.
How it works
- Make-up: a third climbs of 9 to 18%, a third rolling, a third varied descents.
- Homologation: courses must be approved by FIS, with a few exceptions.
- Height difference: at most 100 m on a 5 km lap at the top level.
- Total climb: 25 to 42 m per km on laps over 5 km.
- Altitude: the high point at most 2000 m at top events.
- Width: from 3 m for classic interval races to 9 to 12 m for free mass starts.
- Classic tracks: 17 to 30 cm apart, 2 to 5 cm deep.
- Stadium: a 50 m start zone, a finish zone of at least 50 m, exchange and pit areas.
The glossary has the course homologation, the height difference, the maximum climb, the total climb, the stadium and the set tracks.
Tricky cases
Can organisers make the snow faster with chemicals?
No. Artificial means to improve the glide are banned; chemicals only to firm a soft surface.
A skier takes a wrong turn. Can they go back?
Yes. They may return to the point of the mistake, without obstructing or endangering others.
Must skiers pass every control point?
Yes. Missing one means not following the course.
Are courses at high altitude easier?
Above 1800 m the required climbing is cut by 20%.
Why the rule exists
Balanced terrain tests every part of a skier's game. Climb limits keep courses hard but comparable from one venue to another.
