The first part of the week was dedicated to playing it safe as I babied my tight left calf. Though I probably could have gotten away with the hill workout on Tuesday, it wasn't worth the risk, so I kept Tuesday's activities to 2 miles of easy jogging plus my old friend, the arc-trainer.
I'll say it again, you really can get a very good tempo workout on the arc-trainer.
By Wednesday, everything felt fine, so I resumed my normal running plan, though I still played it very cautious for the first half of Friday's workout, to make sure everything was kosher. Everything held up well, so out of the woods on the left calf.
I do have some lingering concerns though - I've felt the last few weeks like my form isn't quite where it should be - especially my glutes (especially the left), which don't seem to be firing quite right, causing imbalances all over the place. The result is that I seem to have all sorts of intermittent shifting aches that go away with rest, and return with running. So, focus for the next few weeks is on glute activation stuff and drills (which I've slacked off on the last 2 weeks) to get myself back into good form.
