We claim the ornamental design for an educational walking track, as shown and described.
The single FIGURE is a top plan view of the educational walking track showing our new design.
It is understood that the pair of shaded rails that make up the tracks are solid and that the cross lines connecting the tracks are also solid. The octagonal shape in the center is understood to be an open space, and all the areas between the rails and cross lines and all the areas between the tracks are understood to be open spaces. The tracks and the cross lines connecting them are understood to have a minimal thickness.
