How does a ski mountaineering sprint work?
B · Beginner · Races and categories · 2 of 3The sprint is a loop of 60 to 100 m of climbing, two parts on skis with skins split by a foot section, then a descent through gates and a skate to the line; the best take 2:30 to 4:30. A time trial seeds heats of six, then semifinals and a final, with lucky losers filling places.
How it works
- Climb: 60 to 100 m, with a foot section of 10 to 25 per cent of it.
- Qualification: a time trial, one athlete every 20 seconds.
- Heats: four with 24 to 29 athletes; five with 30 or more.
- Small fields: 12 to 23 athletes go straight to semifinals.
- From heats: top three of four heats, or top two of five plus two lucky losers.
- Final: top two of each semifinal plus two lucky losers.
- Start places: chosen in order of the previous phase.
- Rest: at least 20 minutes between phases.
The glossary has the sprint race, the qualification (sprint), the lucky loser, the interval start, the skating corridors and the gate (ski mountaineering).
Tricky cases
A sprinter reaches the pre-start tent late. Can they race?
No. They must be there 3 minutes before the start or they cannot start.
A false start in a heat. Is the heat restarted?
No. The race goes on and the penalty is added at the finish.
Bad weather. Can heats be skipped?
Yes. The Event Jury can send the best six from qualification straight to the final.
Can a protest be made after a heat?
No. Protests are not allowed in sprint qualification, heats or semifinals.
Why the rule exists
Short heats give side-by-side racing that spectators can follow. Lucky losers make sure a fast athlete in a strong heat still goes on.
