Hanging & collecting controls at Cambus, walking due to having started de-training phase of medical research (4 weeks of only 10 mins high intensity training each day).
Right thigh a bit tender from 2 muscle biopsies so probably best to avoid running anyway.
Craig lash road to quarry then down through Sluie to Potties and joined Deeside Way here...
pace run29:00 
pace effort from Potties to home, through Kinker and up Deeside Way. Eased off on last hill.
Felt crap for first part to quarry turnoff but at Potties started to enjoy things and gradually pushed the pace. Feeling more sprightly than for a while. Dark by end but path is good enough to run in very little light.
