Another sign of returning mojo was that I was lying in bed this morning thinking about how I had to come into work, and should I run first or run to work, or take my stuff to work and run later in the day, or ... and then I just got up and ran. I resolved to limit it to 10 km, having decided I have to be more consistent, but reduce the distance of some of the runs. It went well. I ran 2 km steady to warm up, then upped the pace and stayed at or just over 80% HR for the rest of the run. And I did run exactly 10 km!
