Yesterday I had no time to create it in details... See my solution in 4 steps: CREATE OR REPLACE VIEW bd_segment AS SELECT ST_PointN(geom, generate_series(1, ST_NPoints(geom)-1)) AS sp, ST_PointN(geom, generate_series(2, ST_NPoints(geom) )) AS ep FROM -- extract the individual linestrings (SELECT ...

However, for what you are looking for (get a detailed perspective on hiking from point A to point B), you can implement Tobler's ...

In your case, the best tool is probably the "Path Distance" Tool, which will take your DEM into account to adjust the speed. There is a long description on this page on the option to set the speed. Note that the relationship between speed and slope depends on your travel type. By bike, you go faster downhill than uphill, so this is more like a linear cost. ...
