Twenty-one miles each way? That’s forty-two miles total. At a good walking clip of three miles per hour, that’s 14 hours per day walking, which leaves eight hours for work, one hour for lunch, and one hour for sleep.

The first sentence in the article say 21 miles ROUND TRIP.

Round trip was 21 miles...still don't believe it!!

Twenty-one miles each way?

Yeah, I thought that at first glance, but it's got to be round trip. Uphill each way, though, I'm sure.

I was figuring closer to 5mph, at least in clear weather/path.
