I've run 38 miles in the first 7 days of 2013. That's more than I ran in any 7 day period in all of 2012. The biggest 7 days in 2012 totaled 34 miles. Part of the reason I was able to run so much is that I was at the "job market" in San Diego from Thursday night until Monday and I finished my obligations after Saturday morning so I went for one nice 8 mile run and a 9 miler the next day. I don't always have that kind of leisure.
I was thinking about trying to make running a more regular thing. We'll see how that goes. For now I'm considering taking a day off.
