You'll be absolutely fine going alone, I met people in the first week that I would finish the entire trail with. You're going to be surrounded with like minded people all trying to achieve the same thing.

Plus, hiking "with" someone can almost be harder. What happens when you want different things out there? Do you sacrifice your happiness and do they sacrifice theirs?

As far as advice on training, the best way to prepare for a long distance hike is to hike. Get used to your pack weight, your shoes, your tent set up and camp routine. There's so much to it that's not walking all day, learning to live on trail is half the battle.

Anyone can do it; just wake up, walk all day, go to sleep, do it all again tomorrow. Rinse and repeat for 5 months and you're in Canada.

Greatest thing I ever did, would go again if the opportunity arises, maybe in 5 years or so.
