[[Ski orienteering]] is a form of cross-country skiing competition that requires navigation in a landscape, making optimal route choices at racing speeds. Standard [[orienteering map]]s are used, but with special green overprinting of trails and tracks to indicate their [[Navigate|navigability]] in [[snow]]; other symbols indicate whether any roads are snow-covered or clear. Standard skate-skiing equipment is used, along with a map holder attached to the chest. It is one of the four [[orienteering]] disciplines [[Sport governing body|recognized]] by the [[International Orienteering Federation]]. Upper body strength is especially important because of frequent double poling along narrow snow trails.<ref>{{cite web| title = Ski Orienteering
