I noticed in the latest issue of Backpacker Magazine that they have started listing the "Lifetime Miles" for the people they quote in the magazine. My first thought was who keeps a record of their lifetime miles? I assume that the number is an estimate.
I then tried to estimate what my "Lifetime Miles" would be. I wonder if there are any commonly accepted rules for determining which miles to count? For example, my wife and I walk 3 miles a day, six days a week. Do those daily walks count toward my lifetime miles or do I count only the miles done on a hiking trail?
I wear a pedometer that shows how far I walk each day. The daily average is a little over 5 miles a day. Do thoses mile count toward my "Lifetime miles?"
The highest number of the experts listed in Backpacker Magazine was 20,000 lifetime miles. I did a quick calculation -- if I added up my "normal" walking (5 miles a day X 66 years), I come up with 126,000 miles. It seems obvious that they are not counting all of their walking, but I found no explaination of what it takes to count as a "lifetime mile."
Do any of you know the rules for estimating a "Lifetime Mile?"
