LW10 is a para-Alpine and para-Nordic sit-skiing classification for skiers who cannot sit up without support. For international skiing competitions, classification is conducted by International Paralympic Committee (IPC) Alpine Skiing and IPC Nordic Skiing, while national federations such as Alpine Canada handle classification for domestic competitions.
In para-Alpine skiing, the skier uses a mono-ski, which is required to have breaks on both sides of the ski. The para-Nordic sit-ski configuration has two skis. Skiers in this class use outrigger skis for balance, as leverage to right themselves when they fall, and for turning. A factoring system is used in the sport to allow different classes to compete against each other when there are too few individual competitors in one class in a competition. Factoring for the 2011/2012 alpine ski season was done based on subclass, with LW10.1 factoring being 0.7234 for Slalom, 0.7794 for Giant Slalom, 0.7942 for Super-G and 0.8004 for Downhill, and LW10.2 factoring being 0.7399 for Slalom, 0.8152 for Giant Slalom, 0.8069 for Super-G and 0.8183 for downhill. The percentage for the para-Nordic 2012/2013 ski season was 86% and for LW10.5 was 91%.
LW10 is a para-Alpine and para-Nordic sit-skiing classification, where LW stands for Locomotor Winter. LW10 skiers cannot sit up without support, which includes people with cerebral palsy in all their limbs. Competitors in this class lack "buttock sensibility".
The International Paralympic Committee (IPC) defined this para-Alpine classification as "a. Disabilities in the lower limbs, no functional sitting balance. b. CP with disabilities in all four limbs (functional classification)." In 2002, the Australian Paralympic Committee defined this classification for para-Alpine as a sit skiing classification for "Athletes with disabilities in the lower limbs and no sitting balance (i.e. Cannot sit upright without support)."
