Abstract:
A wheeled training device for simulating cross country skiing and the like on a surface which is not covered by snow includes a platform member and a support rod which is secured to the platform member and extends at each end past the platform member. A pair of longitudinally spaced wheels are provided, one being secured adjacent each end of the support rod. Each wheel is spaced from a respective adjacent end edge of the platform member. The platform member is tapered toward one side edge of the device so that the device can be tilted toward the tapered edge, to simulate a ski edging motion, without dragging on the ground.
