If you were flying:
Well the average commercial jet liner travels about 550 mph and the earth is somewhere around 26,000 miles in circumference. If you incorrectly assume it could make the trip without refueling it would take over 47 hours. (A large commercial jetliner has a range of about 5,000 miles so you would need to land and refuel several times).
The record time set for a non-stop around the world flight was in a military B-52 in 1980 at 42 hours 23 minutes. It was refueled in flight and is not an option for commercial aircraft.
The solo non-refueled flight record was by Steve Fossett and took about 67 hours.
If you were walking:
Your feet would probably bleed because you've been walking all day and night for a thousand days.
The world is 25,000 miles around, but half of that is the Pacific Ocean, so let's say 13,000 miles. If you can average 130 miles per day it will take 100 days. That would not be a very interesting trip.
Here is the longest straight line trip on land, 8,444 miles:

More than just 1 week, but more than a year and probably more than a month or two.
