I also went out to beat the rain, but my run ended up a walk. Something is going on with my left heel. It's not from running. I don't know where it's from. I felt it yesterday morning when I was riding and then for a good part of the morning, when I stood up after sitting for awhile. It doesn't hurt immediately after I get up in the morning. I keep thinking plantar fasciatis, but I've had that and it is presenting a little differently. It's like a dull ache and a spasm when I stand up.
So, I ran down the hill 1.3 miles and walked back up the steep side of loop, another 1.3 miles. Walking made it hurt a little more, but the running seemed to make it ache for a longer time after I stopped.
