There simply is no better way to start a Monday than with a long run. I love the feeling of getting a bunch of miles done before work!
I had this same 90 minute run (amazing that I spent an entire 4.5 minutes waiting at stoplights between the local park and the trail...I guess that's the downside of rush hour timing) a week and a half ago, the morning after my dad's heart attack. It was nice to see how much faster I could run it - all at an easy pace - when I was well rested!
I finally went and looked up what that Pa:HR number means in the data analysis section. It's a metric for decoupling as a measure of aerobic fitness and a number under 5% is preferred. As I negative split this run quite well with minimal increase in heart rate, my Pa:HR of 1.82% makes sense!
I hope everyone has a great week!
