I have taken 9428 steps with my over four mile walk. During my walk, my heart rate reached 153 bpm. Unfortunately, due to an apparent bug, this time I cannot tell how long I have maintained that heart bpm. However, my average heart rate from walking was 132 bmp. So there was some cardio exersize going on here.
Between 133 and 146 is my target heart bpm range for a good cardio workout. I used the formulas provided by the following article from the Mayo Clinic. It does state this range is to be used as a guide only which I am sure is conservative. This article also gives a safe maximum heart rate for me of 160 bpm, which I have reached once in the past.

I have burned 392 calories. This added to my 2150 target makes for 2542 calories as my target for today. By the end of the day, I will have consumed about 2500 calories, which is detailed in my calorie chart below. Unfortunately this does not provide me any room for goodies.

Maybe I will sneak in a half of an almond joy candy bar.
