Today would normally be a running day. But, I've had a nagging lower right leg thing that's bugged me off and on for a month. So, I'm going to give it some time. But, I don't want to just sit there and get rusty - oh no, no, no. The compromise was a good walking session on the sweet Landice L7 treadmill.
I played with speed and incline, but settled at 3.3 mph at a 5% grade. I checked my heart rate after twenty minutes. 115. "Holy cow, that's low", thought I. So, I moved the incline to a 9% grade and checked it five minutes later. 138. Better. So I went another twenty minutes at 9% and 3.3 mph and my heart rate was 145. In total, I went 2.5 miles in 45 minutes and burned 460 calories.
Let's put this in perspective. During C25K, I would do my warm-up walk at 3.3 mph with a 1% grade and after 5 minutes my heart rate would be 118. Today, after twenty minutes of 3.3 mph with a 5% grade, it's 115. That's a heart getting stronger.
Now, if my leg would get with the program, I'd like to ask my heart to give me a few 11-minute miles. But, one day at a time, right? I can say one thing: my legs feel better right now than they have in awhile. I think this "tough walking" is very therapeutic. I've gone up the stairs two at a time without holding the rails, which is light-years from where I was for the last few weeks of the C25K program.
