More Walking and Running

Yesterday morning I went for a walk with The Wife for a total of 3 miles. I had the opportunity to get out for it before work.

This morning I walked with her again for a little over a half-mile and then I took off for a little running. I ran four intervals: .5 miles, .7, .9, and .5 again, for a total of 2.6 miles out of 4.4 total. If I can keep this going then I should be back to running continuously again soon.

I became curious about maximum heart rate during the run since during the longest interval I went up a rise against the wind and my watch showed heart rate of 162. I know I'm not in prime shape, but my memory of the maximum heart rate formula is 220-age, which means 165 would be the number. And I'm no mathematician, but 162 is pretty close to 165. I didn't feel like I was pushing that hard, though, and I know how it feels to get to max heart rate. I just looked it up and one formula for fit people would put my max at 175, and another for people over 40 would be 170. Both of those sound more realistic based on how I felt at that point in the run. Not a major deal but like I said, it did pique my curiosity.
