In the end , you got to be the judge.
it is ~ 5 miles from Brunswick to Harpers Ferry.
Round tip without sightseeing is 10 miles.
A casual walk is 2.5 miles per hour.
four hours of walking barely raises a sweat with me. The conditional line is that you claim you are not a hiker. Does that mean you hit the wall after 2 hours? If you have to ask the question, try a two hour hike around home and see if you are still into it.
