Ran at ascending effort for 3 miles then slowed to finally stop. Hampered by the fact I re-tore some rib cartilage while turning over in bed, making it uncomfortable (but not too painful or impossible) to take deeper breaths. Thought cartilage had healed but it's obviously weakened from major damage from fall years ago, then re-injury last year bending to grab cat - at least it's not agony, maybe just the last healed threads came undone and it will heal as full as possible in time. Could do without injuries at the moment - I bend and stretch with my runs no problem, touch my toes, fine - but turning over in bed and my body goes NOOOOOOOOOO!
