After last Thursdays run (W2r1 repeated) I have struggled with painful knees during run and sometimes hips and ankles. Ran again on Saturday and really felt it in joints. Muscles very stiff, stretching daily. Tonight i decided to brisk walk for 30 minutes instead as don't want to risk injury. Bit disappointed as I trust all comments and advice on here about it getting easier, it just doesn't seem to be getting easier for me.
