Walking Around the World

I really want a pedometer for my birthday.
I want to walk a mile, see how many steps I take in a mile.
I would probably need to walk like ten separate miles and find my average number of steps per mile, then I would use that number for the next part of my plan.


There are 24,901.55 miles around the world at the equator, so I want to see how many days it takes me to walk around the world.  


This would be done by multiplying my average steps per mile by 24,901.55 and then keeping track of how many steps I take a day.


So, I would have to keep the pedometer on at all times, but this would be fun.  


It would probably take a while, but I want a pedometer even if I don't do this.
