How can I download a route in gpx format from open street maps?

When you say "a route" what do you mean? Perhaps:

• A signed long-distance foot or bicycle path?

• Directions by some mode of transport from one place to another place?

Hi and thanks for your answer. I mean the path displayed on the map. I can see, for example, a patch on the map, and at the left I can see the names of the streets. I think that the patch is done, and it should be possible download it... or not :-(?

Sorry - I'm still confused - do you mean "all the streets that you can see at (for example) https://www.openstreetmap.org/#map=17/54.01271/-0.98989 " or "a route such as https://www.openstreetmap.org/directions?engine=graphhopper_foot&route=54.01356%2C-0.99216%3B54.01225%2C-0.98943#map=18/54.01290/-0.99080 "

Sorry for my confusion... :-( Yes, I mean the your second example... Here there's another pach: https://www.openstreetmap.org/directions?engine=graphhopper_bicycle&route=44.4938%2C11.3430%3B44.8394%2C11.1432#map=10/44.6671/11.2335

In this case I can see the patch, but is it possible download? Thanks!

I'm afraid I don't know the answer and someone else will have to answer that.

I suspect the answer is "no", and you might need to go to the routing provider, in this case https://graphhopper.com/maps/ . There a GPX export is available.
