Roller skating is not a winter Olympics event. The ice events of the Winter Olympics include short track speed skating, speed skating, figure skating, ice hockey and curling, while the snow events include snowboarding, freestyle skiing, platform skiing, cross-country skiing, nordic combined, biathlon, alpine skiing, snowmobiles, steel snowmobiles and sledding.

Due to the different venues of sports events, the equipment needed for ice events and snow events in the Winter Olympics is naturally quite different. Athletes in ice sports use special skates, while athletes in snow sports slide on the snow with the help of skis, sledges, snowmobiles and other equipment.
