Abstract
A runner traverses a long distance by running back and forth over a short pathway or lane laid out on a floor and at each end of the lane reverses his direction by partially turning just before striking one of a pair of resilient backstops, each pair having an inverted U-shaped frame, placed at the ends of the lane. In other cases a backstop may be used at one end only of the lane, the runner thus traversing the lane only twice. Each backstop, due to its angle with the floor, rebounds the runner back in the opposite direction at substantially the same speed at which he struck the backstop. In these manners and with such apparatus not only can longer distances be effectively run over relatively short lengths of gymnasium floor, for instance, but various types of foot races can also be conducted indoors.
