Welcome to the wonderful world of OpenStreetMap and, as marto said, Open Elevation. Here is a query to get you started with the latter: https://api.open-elevation.com/api/v1/lookup?locations=41.161758,-8.583933 (not sure lat/lon or lon/lat).

Try this at OpenStreetMap query at the sandbox at: https://turbo.overpass.kumi.systems/ :

{{geocodeArea:Spokane}}->.searchArea;
way["highway"="path"][!foot][!bicycle][!segregated](area.searchArea);
(._;>;);
out;
