Ice cross downhill is a winter extreme sporting event which involves direct competitive downhill skating on a walled track featuring sharp turns and high vertical drops. Ice cross downhill is similar to ski cross and boardercross, except with ice skates on an ice track, instead of using skis or snowboards on a snow track.

Winter sports or winter activities are competitive sports or non-competitive recreational activities which are played on snow or ice. Most are variations of skiing, ice skating and sledding. Traditionally, such games were only played in cold areas during winter, but artificial snow and artificial ice allow more flexibility. Playing areas and fields consist of either snow or ice.
