I would like to do a virtual walk along a long-distance route that I have plotted in Google Maps. By virtual I mean I will be walking locally and mapping my distance onto the route. So if I walk 10km one day, and 20km the next, I’d like to say to google “show me the point along this route which is 30km along” to see where I have (virtually) reached.
I am aware of the distance measurement tool but that’s not what I’m looking for - that’s for straight-line distance.
I’m not completely tied to using Google Maps for this, so if there is another mapping tool that does this, I’m amenable to switching, although I’ve got the route already defined in Google so I’d rather use that.
