This OP question really brings back the memories haha. Young and ambitious, with little experience in what really matters, the course of your trip, not how far ya make it.

When I was graduating college, Im assuming you want to thru hike after you graduate and go on to college, I had big dreams and plans to thru hike and then go on get a job. EVERY SINGLE TRIP I was killing miles, trying to further and further until finally! I had no more hiking buddies!

My suggestion to you two guys would be to start in springer like every one else, take your 60 days 1 day at a time and enjoy the journey..
Get as far as you can and if you don't finish it, you've just done a huge chunk of it and have the rest of your life to finish it on up.

Physically it can be done, realistically? not so much, and if so, will you enjoy it? Probably not.
