Walking to Walmart

I rolled out of bed this morning and neither my legs, nor my back would bend or twist. I am stiff like a stick. My plan is to walk the mile and a half to the Walmart, buy insoles and MAYBE jog home. I would say it has been a while since I'[ve jogged this much, but I never have. At least not out in the world. I used to do 5-6 miles on a treadmill, but even that was when I was 19/20. Yeesh!
