Really enjoyable. Not sure if that's the point of a long run, but it's important in my book. Took a long time this morning designing a new route to S Boulder, tinkering around to get the exact mileage in the 14.5 ballpark. It was tricky, but I was satisfied with the result. Then I went and ran it, and I took a couple wrong turns, and I added on a bit going over Wonderland Hill, and the mileage was all outta whack. But I felt good and relaxed. I found myself overthinking the goal of this long run, and when I started out my mind was really chattering away. I was running quick but I wasn't sure if that was the right idea. So I stopped concerning myself with pace, and just occasionally checked HR and cadence. Both were typically fine, so I didn't worry. I tried to simply enjoy the new surroundings, and it wasn't hard. I was running along some beautiful stretches next to the creek and on campus. CU was pretty deserted, but most of the multi-use paths through neighborhoods were very busy. I was cognizant of the 6 foot guideline to avoid exposing myself or exposing others to anything I have. I'm embarrassed to admit I employed a breath-holding technique a few times. But running is hard without O2.
I definitely felt myself wearing down at the end. My HR trended slightly upward during the run, which could be for a couple of reasons: a) I was running in the "heavy" domain (below "severe" but above "moderate"), where the body slowly increases its O2 uptake and reaches a steady state after a long time. But the length of time of my HR increase was much longer than the 20-60 mins required to reach the higher steady-state O2 uptake. Also, I believe the lower bound of the heavy domain is lactate threshold, which was not what I was up to today. So more likely, it is b) it was cardiac drift associated with dehydration. Some say that as the blood volume diminishes, the heart speeds up to compensate. Lower stroke volume, but higher rate. Others say the increased HR is from pumping blood to the skin. Either way, it's well-known that getting dehydrated during a run increases HR. Analysis complete for now beep boop
