A running exerciser structure, a front end of the running board frame is pivotally connected with a second board of a linking mechanism. When a driving motor of the linking mechanism drive a threaded rod to forward or backward rotate, a first and a second threaded bushes are moved along the threaded rod opposite to each other. At the same time, a first and a third links and a third and a fourth links are driven to move opposite to each other. The second board can be continuously ascended or descended and the running board frame is upward or downward inclined to form an upward slope, a downward slope or a plane face. Therefore, a user can upgrade or downgrade or horizontally run on the running board to exercise his/her body to different extents.
