Chariots of smoldering embers

So I've taken up running. This has been a slow jog in progress since probably mid to late September. Today, I successfully finished 2.5 miles in 31 minutes, and my one mile time was 11 minutes; not too shabby. I'm definitely feeling stronger and my stamina is there, but fatigue and I are now best friends. I sleep awesomely, deep and hard, through the night, and honestly, when I come home, my futon is my favorite place to rest my weary legs. My original goal was to hit 5 miles by Dec. 9. I don't think that's going to happen, but I am getting close to my goal of a 10 minute mile. I think 3 miles at a 12-minute mile average pace will, however, be very doable by goal date. I'll just stagger and limp my way through the last 2 miles.
