Grade: 2
Ski O effort & then was bending inside car to pick up something, making an overstretch - which I felt. Nothing Mon & Tu until 24' into a jog in Newton. Then moderate discomfort - walked & jogged back to car. An hour or so later, was limping & unable to stand - ice & 800mg ibuprofen.
Decided calf issue is past. No way to have foreseen. And initial incomplete rest. Running on irregular surface exacerbated less I'd guess.
