Summary of my progress: Last week I completed 42 miles, and I'm now around 6:50/mile for my regular 4-mile tempos. My highly structured training plan starts on Jan. 16 (HM is on 04/28). My pre-plan goal was to reach 45 MPW and 6:45 tempo for at least 20 minutes. The former is definitely doable, but that 5 seconds per mile on tempos seems a bit harder...
