Week 11 ended with optimism. Threshold was back, the long run finished at marathon pace, and the chassis appeared to be behaving.
Then the right knee revolted.
Most of the week became:
Pain. Medicines. Rest. Physiotherapy. Repeat.
No threshold. No Zone 2. No long run. After several weeks of rebuilding, the knee clearly wanted a different training plan.

By the weekend, I finally tested the waters with a couple of slow walks — about 3.1 km Saturday and 6.8 km Sunday. Nothing resembling running. Just getting the legs moving and checking how the knee responded.
The temptation, of course, is to calculate the damage: kilometres missed, fitness lost, November races, February marathon.
But an angry knee doesn’t negotiate with an Excel sheet.
So Week 12 wasn’t really a training week. It was a healing week with a couple of walks thrown in.
Last week:
Engine ON. Chassis behaving.
This week:
Engine OFF. Chassis back in the workshop. Test drive restricted to walking speed. 😄
