You can get a lot better, just keep it up. Continuing to do it after becomes a chore is crucial to getting better, but don't push too hard at first.
As others have said, how far you can do depends greatly on the terrain and load you are carrying. Also how many days in a row you are going to do it. I'm in my late 40s and have found that's the biggest change. I can still hike about as far as I could in my 20s (though I can no longer carry as much), but I can't do max distance multiple days in a row.
I recommend alltrails.com to find trails around you and see how long it takes other hikers. The average time spent and the trail rating can be more useful than the distance. Make sure to look at the vertical too.
Hiking is a great life-long sport! My dad is in his 80s and still does it.
