Cattle are Complaining

I ran ten miles on Sunday as promised. It didn't feel too bad. In fact I broke away from my slow gang to dehyrdate at a nearby park bathroom, promised to meet up about a mile down the road by a different route. When I got there they were nowhere to be seen a quarter mile in either direction so I said f**k it; I need the pace practice. I must have been running 10+ /miles with them and I finished at a 9:03/mile pace so I must have been rolling along pretty hard out there and didn't even notice.
What I did notice was a lingering tightness in my left calf. A cattle call. I believe it came from periods of trying to correct my stride by landing midfoot as opposed to heel-to-toe. It's a strain that I treated with a day off Monday and tested this morning in some intervals (2x1600, 4x400, 4x200). Once I loosened up, it was fine. Afterwards I iced and ibuprofin-ed it.
Tomorrow I will see how I feel when I wake up. I'd like to go 3-4 but the plan allows for rest if desired.
Speaking of rest, I'm going to make like Mia and go try some modifed bedrest.
