A plurality of longitudinally extending straight and curved, slide segments, the upper ends of consecutive ones of which are overlapped by the lower ends of the preceding segment to define a continuous, sledding run having a predetermined configuration, including straight and curved portions. Each segment is of generally trough-like configuration and has a cross-sectional configuration comprising a shallow, concave central sled-supporting portion terminating in convex side rail portions. The convex side rail portions have a generally inverted U-shape cross section with depending flanges extending integrally and downwardly from the outer portion thereof. Butt straps removably fastened to the depending flanges interconnect each slide segment to an underlying support. The underlying supports consist of universally mounted and adjustable struts each having a tube-shaped rail insertable in the inverted U-shape of the slide rail portions. Only one strut on each side of a slide segment at one end thereof is necessary. A plurality of spaced apart ground supports are positioned along the run supporting the universal mounts of the struts. Cables having turnbuckles extend between each ground support and the next succeeding strut downhill thereof. A ski lift may extend between the ends of the run.

DETAILED DESCRIPTION OF THE INVENTION FIG.
1 shows a mountain slope with a ski lift leading to the top.
Adjacent the upper terminal of the lift is an entrance for the new mountain slide 1 which runs with a proper inclination in a predetermined course among the trees.
FIG.
2 shows the arrangement of the individual new slide segments on their supports.
As illustrated in FIGS.
1 and 3, each segment of the slide 1 rests on both sides on struts 6 seated through base portions 7 in brackets 4 mounted on ties 3, which ties are secured against movement by rods 2 driven into the ground.
Each strut 6 is connected to the tie 3 located immediately above or uphill thereof by a stay 14 consisting of a cable adjustable by means of a turnbuckle 15.
Each segment of the slide 1 is overlapped at 1A' providing support for the lower end of the next uphill segment.
FIG.
3 shows further that both sides of the hollowed out or dished slide surface 1a of slide 1 include rims 1b which arch upwards and continue in a flange 1c flared outwardly and downwardly from the slide surface.
The arched rims 1b rest on rounded supports 11 which advantageously consist of pipes welded to the struts 6, which are advantageously in the form of threaded rods.
In order to keep the strut 6 connected to the slide 1, the flange 1c is provided with a butt strap 12 having a leg 12b directed inwardly and defining therein a hole 12a through which the strut 6 projects.
In order to allow for minor lateral movements, the hole 12a has a diameter larger than the diameter of the strut 6.
In order to avoid any failure of the slide, which preferably comprises asbestos concrete slabs, in the areas where the butt straps 12 are attached, the screws 13 for the attachment of the butt straps 12 are directed through reinforcing plates 16, so that any deleterious forces of the butt straps 12 are absorbed by the larger areas of the flanges 1c.
In order to adjust their elevations, the struts 6 are threaded into hollow, tubular base elements 7 provided with threaded adjusting nuts 8
