Let me recomend a run just at sunrise. It’s pretty enough to keep you distracted from aching lungs and shins and cold enough to keep you alert.
Those of you in the northern hemisphere might want to wait for spring to attempt this. It’s bound to be a wee bit cold. The good news is that sunrise is later for you all so you’d get to sleep in.
I have a happy heart and feel oodles better than yesterday. May that always be said of each of us!
