I just added up my miles for the year and I have, according to my not-so-precise calculations, 3859 so far for the year. So, to get to 4000 I'll need to average just over 10 miles a day for the next three weeks. What do you think? Is 4K worth it? The last time I ran 4K in a calendar year was 2004. I'd be curious what the readers of this blog think.
