Ok so don't laugh at my mileage... I'm in Canada  ;-)
I started walking daily a month ago but only just saw this thread. in the last 27 days, i've been walking at least 5 miles a day.
Start Date:   Oct. 25, 2015
My approximate mileage as of 12/13/2015  :   230 / 2075     Approx. trip date:   10/14/2016
Now that I've found this thread, I'll be taking much better notes of my daily mileage!
