This varies a lot from person to person - for some people it might be 20 miles a day, for others it could be 80 miles.
Luckily you are close to the trail, so you can go out there and take some test rides on weekends. Maybe try riding just 5 or 10 miles out and 5-10 back. If you still feel good, do another 5+5 or whatever feels attainable. Try again the next weekend, adding distance, to see what feels right.
Don't just go out and ride 50 miles without a little advance riding, or it will not go well. You might be in great cardiovascular shape with strong legs, but your butt will be screaming if you you haven't gotten some "saddle time" in advance.
So that's not a very straightforward answer, but it's (I think) good advice. Once you get out and do a few long rides, your body will tell you the ultimate answer of what distance works for you.
Good luck and happy trails!
