While I've lived 1.5hrs from the park my whole life, I've never hiked the AT through it. This will be my first bigger trip and I'm unfamiliar with the terrain. I know from Waynesborro to Front Royal through the park on the AT is about 107 miles, I have 11 days to do it. Will the terrain make 10 mile days difficult? Or is that a reasonable expectation of daily mileage for a fit person with a reasonable load?
