Yay! I had two good runs this weekend. I still can't run more than 4 miles at a time without my hamstring complaining, but I'll take it. I adjusted my anti-thyroid meds downward again this past week. It may or may not be coincidental, but I felt less aerobically challenged during my weekend runs. My meds were making me slightly hyper and that, it turns out, could have been the cause for my erratic heart rate.

The only thing that worries me is that I really just want to run. I haven't felt a huge urge to ride any of my bikes in a long while. Perhaps with warmer weather returning, I'll change my mind.
