Moving up to the "medium-fast" group in running club is helping get my speed and weekly TSS up. Did 7.4km at 4.39m/km (first time it's been sub 5m pace this year) on Monday, decent SST session on Zwift on Tuesday, then did hill reps with the club last night. I spent most of the reps being last to the top, but for the last 3 I managed mid pack - still I was fit to puke by the end, and my left calf and achilles are tweaky this morning - the session was 107HRSS, with a HRSS/hr of 87.4, but that's because we ran to the place we did reps and back. My LTHR is 165-168, and my best 20m last night was 166. It was really tough.
Looking back at 2017, I spent from BCM on in the run up to LEL at ~100CTL, but in prepping for my hernia repair in the January, I was up at 126CTL. My homelife was miserable, but damn, I felt strong.
