I am a c25k grad. and have one official 5k under my belt...on a workout run this past week in the very cold weather, I finished with some pain in my left lower leg, upper ankle. It's in the spot that would be opposite of my shin. I iced and wrapped tight, then ran a Turkey trot the next morning. Then both legs hurt in the same place. What muscle or tendon is that and how did do that? I have been resting , wrapping and elevating it now. Wandering if it's just cold weather running or cold muscles???
