If I had continued my 365 consecutive days of running, I'd be in the short rows now. Obviously, that's not the case though. It doesn't look like I'm going to be starting over anytime this year either. If you observed my repeated attempts and fails from April to September of last year, you'd probably agree. It's just not feasible when I'm teaching, in grad school, and have a rinky-dink treadmill that shakes the whole house and prevents others from sleeping.
I think 31 days is pretty feasible though, so I'm going to end the rest of my running (not calendar) year with a few last meager goals. It's less than a month until my birthday and I'm celebrating the last days by running each day and finally finishing Jillian's 30 Day Shred! It's my birthday present to myself and hopefully I'll enter this next year in a little better shape.
I'm only 3 days, 5 miles, and 3 Shreds in, but I feel so much better having that commitment each day and not being able to talk myself out of it!
