I did 7.5 miles in the a.m., avg. HR 146. The course was up and down in mid-town, so not the best. My HR spiked a couple of times, but certainly I kept it right where it needs to be.
A few hours later I got in another 4.5 miles on the treadmill, avg. HR 146. I ran a total of about 1:45 today, pretty slow but that's the show for now.
The key was to get in some miles; I could have done more, but I need to be patient. A good day.
