|Notes||Very strange ... run ... turned walk this morning. So the plan was for a super easy recovery run of 2 miles. I decided I'd force the "super easy" part by strapping on my heart rate monitor and, using the Maffetone 180 formula, keep my heart rate at 133 or less. Well, my heart rate kept spiking up dramatically. So much so that I thought it had to be a problem with the monitor. Determined to stay below 133 bpm, it turned into a fast walk. About a half mile from home, it occurred to me that I should try breathing in repeatedly with all my might. This brought my heart rate down and reduced the volatility in rate. As I kept this up while jogging, my rate stayed below 133 for the most.|
Is the logical conclusion that I'm not getting enough oxygen while running and breathing normally so my heart is compensating by pumping a lot harder? I've got no other theory so I'll go away and think about it some more ....
