Ok, so I've enjoyed and really appreciated using gpx tracks that others have made and since I get around a bit I thought I might return the favor and start creating my own to share.
What's the best way to do that? I'm assuming the GPS has to be on every second you're hiking.
What about trails that take multiple days and require the GPS to be turned off at night, batteries swapped out, etc.? Is there a way to maintain continuity?
