Invention herewith described refers to a device for running has a novelty in that it consists of a base (1), stays (2), a screwed spindle (3), with a nut (4), a spring (5), a support frame (6), a bearing (7), rolls (8) with journals (9) and belts (10). The base (1) and the supporting frame (6) are made of steel pipes of rectangular cross section. The supporting frame (6) rests on the base (1) at one end over the stay (2), and at the other end over the springs (5) or the screwed spindle (3) with a nut (4). The nut (4) is at the protruded part (14). Journals go into the bearings (7) of the rolls (8) over which is drawn a belt (10) for running. The spring (5) is set in the bushes (12) and (13). When a man steps onto the belt (10), the spring (5) bends and the supporting frame (6) comes into an inclined position and therefore the belt (10) starts its moving. The inclination of the supporting frame (6) can be different and by means of the screwed spindle (3) that swivel through the nut (4).
