What are the classes in para cross-country skiing?
B · Beginner · Categories and classes · 2 of 3Vision impaired skiers are NS1 to NS3; NS1 has no usable sight. Standing skiers are LW2 to LW9: LW2 to LW4 have leg impairments, LW5/7, LW6 and LW8 arm impairments and LW9 both. Sitting skiers are LW10 to LW12, with half classes, set by trunk function tests. New athletes race in the highest-factor class of their category.
How it works
- NS1: light perception at most.
- NS2 and NS3: partial sight.
- Vision minimum: LogMAR 0.9 or a 60-degree field.
- LW2 to LW4: leg impairments.
- LW5/7, LW6, LW8: arm impairments.
- LW9: arm and leg.
- LW10 to LW12: sitting, with half classes.
- New athletes: NS3, LW4 or LW12.
The glossary has the standing classes, the sitting classes, the vision impaired classes, the new athlete class, the eligible impairments (para Nordic) and the sport class change.
Tricky cases
Must an LW2 skier use two skis?
Yes, and two poles.
A skier's class changes mid-event. When does it apply?
From the next race.
Are earlier results void after a class change?
No. They stand.
What class does a new sit-skier race in?
LW12.
Why the rule exists
Classes follow how much each impairment affects skiing. Putting new athletes in the top class stops them benefiting from not being classified.
