How big are the Territories

Hi All

How long would it take a typical mouse guard to walk from Lockhaven to Barkstone? I’m trying to get a handle on how big the Territories are and I can’t seem to find it in the rules.

The figure I’ve seen mentioned around here is 1 inch on the map inside the jacket of the game is one day travel time. Calculate from there.

Thanks.
