The average moderately active person takes around 7,500 step/day. If you maintain that daily average and live until 80 years of age, you’ll have walked about 216,262,500 steps in your lifetime.

Doing the math, the average person with the average stride living until 80 will walk a distance of around 110,000 miles.

Which is the equivalent of walking about 5 times around the Earth, right on the equator.

So:

Q: How far does the average human walk in a lifetime?

A: About 5 times around the Earth on the equator.
