Abstract
A sled having a planar platform with tubular runners mounted for pivoting and sliding at points fore and aft of the platform. Because the runners can pivot and slide at the fore and aft points, the entire length of the runner can be bowed for increased maneuverability. The runners are of low friction plastic tubing for speed and are mounted by means of clips which allow for sliding, pivoting, and easy replacement of the runners.
