Modern humans think of a hundred or so miles in terms of a comfortable trip in Air/conditioned boxes.

When TSHTF you can be certain that if you live in a city relying on freeways to get out of town - a million or more people will have the same idea. Those freeways will become parking lots.

Even if only SOME of those people decide to take street roads and you are one of them, you will most likely find your vehicle standing still.

Today the modern freeway is set at 65-75 miles per hour. It takes about 85 minutes (1 hour 15 minutes) to drive.

A horse with a rider and little provisions “walks” at 3 to 4 MPH, on average that is 3.5 MPH. that is about 24.5 hours to travel 100 miles. Or about 28 miles in an 8 hour day.

Most people walk at 2.5 to 3 miles per hour let’s say most walk at 3 MPH – it takes 33 and a third hours to travel 100 miles. Assuming they are traveling light. 24 miles in an 8 hour day.

Of course neither horse nor man can walk a day nonstop. They need to stop for food, rest, drink. It will be three days to travel 100 miles.

Assuming a 10 hour travel day, you will travel about 35 miles on horseback, 33 miles on foot – IF you stick to the roads which are nicely paved, level and have bridges and all of those wonderful conveniences that make travel faster.

If you have no roads, and have to cross streams and rivers without bridges, you are traveling like the covered wagons did A wagon might do 15-25 miles in a day.

Now do that with 80+ pounds on your back....
