An ascending/descending and folding structure for running exerciser. The running board frame is connected with a linking mechanism and driven thereby. A telescopic tube assembly of a supporting device is telescoped so as to move the caster support back and forth for adjusting the inclination of the running board. By means of rotating a threaded rod, a long sleeve of the linking mechanism is telescoped into a short sleeve, whereby the running board frame is turned upward. Therefore, the running board can be electrically folded. In the case that there is no power supply, a user can directly manually turn the running board upward and fold the running board.
