Suffering Benefiting from mature onset exercise addiction and low aerobic endorphin release threshold. Hoping there is no cure.
Great news...going back is scary. Every step causes some worry. Use the Pfitz work-out and stick to it is all I can say. The schedule starts out with walk-runs which are more walking than running. It gradually builds up to running. After first few weeks you may be tempted to skip as you run more but I would recommend sticking it out till end of schedule. I also learned after Pfitz all the training errors I was doing.
Now I try to keep to a schedule with rest days [for cross training] and varying types of runs -even when not training for a race. I also observe the 10% weekly mileage rule as well with fall back weeks in mileage. In addition, I always try to stretch afterwards since muscles in leg can affect how the foot lands and pushes off and vice versa. I also retired the shoes/type that I was wearing when SF happenned.
