I’ve got this route I run that is half woods and half roads. I do not know exactly how far the route is. I do not know if I am running it quickly or slowly. I do not know who’s property I am passing through on the well-trodden path along the banks of the Charles river. I do not know much about this route except that I track my time each time I run it. And my sole goal each time is to improve my time. I do not always improve my time, but usually I do. I do not allow myself greater time this year because I am a year older than last year. If anything, I am also a year wiser and by running this route often I should know where to push hard on the uphills and where to save energy on the downhills. What is important to me is that I raise the standard by which I compete with myself.
