See the walking map I created yourself here!
Note: There's a long (37 day) detour when you walk from Sudbury to Thunder Bay due to the fact there appears not to be any non-highway walking routes between the two cities. If you were to walk beside the highway, you'll only need to travel ~1,005km -- whereas the route via Michigan and Wisconsin is 2,519km saving 37 travel days, a ferry ride and crossing into the United States.
At +51° 23' 47.27", -68° 41' 51.04" you'll see a circle of land surrounded by water. It is known (to some) as "the eye of Quebec". Reply to this entry if you think you know what caused this.
Of course, all this talk about Canada is in honour of my upcoming trip to the Spearhead Run over Labour Day weekend. I will be here from Friday thru Monday.
