Timing and Measuring

There is a "Hot Cocoa" 5k in December where the participants are required to finish each mile in no more than 15 minutes.  That doesn't seem bad if I could get these short legs to lengthen their stride.  Tonight I walked around the block two times.  Got in my car and measured the block to  be .48 miles.  When I walked I took the outside of the road which curves out a lot in three of the corners.  So I am going to say it is about 1/2 mile each time I walk around the block.  Walking twice took 18 minutes. ( I do need to keep in mind that I need to be doing this for three miles and not just one) Since I have til December and maybe I will actually be doing a little more than walking, I am hopeful.
