I've got a pixel watch and would love to use it for navigation while running but (admittedly without much in the way of trying) haven't stumbled across a way to do this. What do you use to make it do that? Strava?
I assume you could set up a "walking" journey with multiple stops as waypoints on your phone then when you press start your watch should pick it up and give you the direct route between each waypoint. Not sure if that would sufficiently provide what you were hoping for.
