My "scree sliding" may have taken me from the rear of the climb to near the front, but a misjudgement of the depth of the stones below Drinking Rock resulted in some skin loss from my knee and shin (but I avoided a fall), so on arrival at the car park I did finally crack open my extensive First Aid pack to clean up and dress the abraisions. A literal "Physician heal thyself! (Luke 4:23)".
Cramps on the ascent did trouble a few people (including myself) despite sufficient fluids, added electrolytes, magnesium and even quinine. Stretching, resting and slowing one's pace are probably better treatments, with better fitness as the best preventer!
