An apparatus for training horses having a series of adjustable obstacles with transverse crosspieces (22; 201; 306; 402; 510), the apparatus comprising a base structure formed by a pair of substantially horizontal and parallel guide rails (2, 2'; 108; 102') disposed on the ground at a predetermined distance from each other, a plurality of vertical mounts (3, 3'; 101, 101'; 203, 203'; 304, 304'; 501) slidably placed upon the guide rails to adjust their longitudinal position therealong. The vertical mounts have vertically mobile supports for supporting and holding the crosspieces at adjustable height. The same number of vertical mounts is disposed on both rails in mutually facing relationship to form pairs, each vertical mount being fixed on a wheeled carriage coupled to first motor means to provide synchronous movement of the pairs along the guide rail. Second motor means act on the vertically mobile support to adjust their vertical position along the guide means.
