Slept pretty soundly only to suddenly wake up at 5:30 a.m. to realize I had a 4 miler planned. I finally understand the need for recovery run done at a recovery pace. I felt so sluggish and was content to settle in for a slowly paced run.
Tomorrow, it's an 11 miler before work, which means yet another 4:30 a.m. (or so) start. Time for bed.
