>>241867413km is pretty good for a nice walk. I find 8km is my sweet spot, and 20-ish is when I start feeling like I'm completely done for the day. As for trails, depends on where you are. If you're in a park then a lot of times going off the trail is against the rules. In my area for example, everything within an hour's drive is all parkland where you're supposed to stay on the (plentiful and well maintained) trails. But once you go further out, you start getting into crown land (public land in Canada) where you can go where ever you please. Been working up to it myself, just been having so much fun doing day hikes that I've been too lazy to get prepped for a proper camping trip.
