I'm thinking about setting a goal to (eventually) thru hike the AT, but right now I'm just a hikkineet who only goes out for short walks at local trails and is a good few years into recovering from anorexia. How realistic of a goal is it to thru hike in '24 or '25, if i start preparing now? what would preparation even look like? my parents are marathon runners and cyclists, not much hiking so idk where to even begin. most exercise stuff i've done is short cycling (max 30 miles), martial arts, and parkour and none of those are quite and demanding endurancewise as i imagine thru hiking to be
