The problem is that Eurovelo (EV) 1 is routed here (https://www.openstreetmap.org/#map=18/38.70112/-9.38946&layers=CN). One has to carry the bike up, which is utterly crazy for a long distance bike route (people normally ride heavy bikes with loads of luggage). Thus I will reroute the EV1 to avoid those stairs. Once I did this change I'll close this note.
