An example from Stockholm. Hammarby Allé is a wide street with a broad sidewalk on on side (both for bicycles and pedestrians) and a cycleway on the other side. See
In OSM this is represented as https://www.openstreetmap.org/edit?editor=id#map=19/59.30192/18.08231
Where the street is tagged Foot=no, because there is a cycleway with foot=yes next to it. So this street, and many more like it in Stockholm never get into Citystrides list at all. But when running I certainly feel I’ve run it! Have do you other striders deal with this? I guess I could also mark the street as foot=yes, since there are no signs prohibiting walking, it’s just assumed you use the sidewalk…
