If you happen to be using OsmAnd as your navigation app, you could experiment with the setting “Minimal distance to recalculate route:”

  • Configure profile (e.g. Walking or whichever mode of transport you want)
  • Navigation settings
  • Route parameters
  • Recalculate route (bottom of screen)
  • Change Minimal distance to calculate route

Other apps may have similar settings, or more basic apps may not give you this level of control.

If I move a few miles on, and select move to here the track may continue along my route or find a new route, I assume a shorter route which I don’t want

The demo/test routers on osm.org do not have a Via function. Moving the To-marker results in recalculation of the route. I seldom use routers online, but I’m sure many mappers can name their favorite OSM-based mapping applications with Via function and many other goodies!

The UI on osm.org has links to the original sites of all three routing engines once you’ve calculated a route (the one for valhalla seems to be broken right now though).
