PURPOSE: A ground ski is provided to function as a ski regardless of seasons and places ad to drive by converting stepping operations into driving force. CONSTITUTION: A ground ski includes a plate part(100), a stepping part(200), an elastic supporting part(300), a rear wheel driving roller part(400), and a front wheel roller part(500). The plate part is in the form of a ski blade. The stepping part vertically rotatably installed at the upper front side of the plate part. The elastic supporting part is installed between the plate part and the stepping part and applies elasticity to the upper direction of the stepping part. The rear wheel driving roller part drives by receiving driving force based on the stepping operation of the stepping part. The rear wheel driving roller part includes a frame, a rear wheel roller, a gear module, and a link(450). The rear wheel roller is rotatably installed at the frame. The gear module is interlinked with the rear roller. The link passes through the plate part to connect the gear module and the stepping part. The front wheel roller part is installed at the lower front part of the plate part.
