How does a cross-country ski race work?
B · Beginner · The races · 1 of 4Cross-country skiers race over marked courses of climbs, rolling ground and descents, using only their own strength. Each race is held in classic or free technique. Some start one skier at a time against the clock; others start everyone together, so the first across the line wins. Sprints, relays and team sprints add knockout and team formats.
How it works
- Techniques: classic or free, set for each race or leg.
- Courses: about one third climbs, one third rolling terrain and one third descents.
- Interval start: skiers start apart and race the clock.
- Mass start: everyone starts together; the finish order decides.
- Pursuit and skiathlon: starts or techniques linked across two parts.
- Sprint: a timed qualification, then knockout heats.
- Team events: the relay and the team sprint.
- Own strength: skiers must cover the whole distance on skis, with no pacemakers.
The glossary has the classic technique, the free technique, the interval start, the mass start, the sprint and the relay.
Tricky cases
Can a coach ski alongside to pace a racer?
No. Outside pacemakers are not allowed; coaches may run no more than 30 m beside a racer to give times.
Is the first across the line always the winner?
In mass start, pursuit, skiathlon and relay races, yes. In interval-start races, the fastest time wins.
Can racers use any technique they like?
Only in free-technique races. In classic races, only classic technique is allowed.
What happens if it is very cold?
Below -20 °C at the coldest point of the course, the race is postponed or cancelled.
Why the rule exists
Mixing climbs, flats and descents tests fitness and skill together. Offering both techniques and many formats keeps the sport varied and fair to different strengths.
