Felt half-asleep for most of the run. After the warm-up legs didn't feel too bad, but just felt tired. 4x 6:00 with 2 min jog, first one around 6:20, last about 6:10 pace. 4x30 hill sprints after. Very cold cd after. Grateful it didn't rain and grateful for teammates that make early, cold mornings not so bad. PM: Spent the day semi-braving the weather and hitting the high spots of STL; zoo, arch, ice sculptures on the loop. Was fed up with the wind by the time we got back and hit up the treadmill. Felt pretty ded.
