Notes
Warmed up 4km including strides to F1 track and ran 5*800m, with 90-110 secs jog in between. Splits: 2.58. 2.58. 2.58. 2.58. 2.57. Just realized that intervals have become a real chore for me now. In the past, my legs always felt good and I was up for doing track work, but with Pfitz program which is more endurance-based, I am struggling with speedier stuff. Did 7k easy cool down for 17km total.
