A brief introduction to other situations of cross-country skiing.

Cross-country skiing competition involves two technical rules: traditional technique and free technique. Traditional techniques include alternating sliding, double stick sliding, eight-step non-sliding stage, sliding down and turning.

Cross-country skiing is not allowed with two feet or one foot. The skis must be placed in the pressed snow trough, and the two skis should be kept parallel to the sliding direction.
