In keeping with yesterday's push, I ran 25 minutes today.
And for today, that was enough.
It was a good workout. I spent a great deal of that time with my heart rate up, and worked up a decent sweat. I felt good throughout, never out of control or in pain.
I think a corollary to yesterday's "aha" moment is the understanding that there will be days that I push myself, searching for those limits in effort to break down those barriers. And there will be days that I just need a good solid, joyful workout. The last thing I want is an injury.
Today was just a good solid, joyful workout.
I feel good.
