I have been running the 25mins of week 7 fairly well, no real problems on the run thankfully. However, the recovery is slow and seem to be accumulating muscle fatigue . Have done the run 5 times now under different conditions but have sometimes needed two rather than one day to recover as the muscle fatigue can be too much. (These muscles are 50 years old and I usually soak them in a hot bath after running with a bit of massaging.) Anyone in this age bracket who has experienced the same? Any special adjustments for these last few weeks?
