Advice for thru hiking setup

Hi All - I have a Fenix 7X sapphire and will be starting the PCT NOBO on April 01.   I think I already have maps factory installed on the watch but what's the best way to get the "bread crumb" trail?  I don't really need real time turn by turn directions, I just want to check in every few miles or at a trail split to verify I'm on the right trail or which branch I should take.  Any advice?
