I ran approximately 11 miles today in 1:31:41, with an average HR of 133. My normal route is blocked due to construction so I had to improvise a bit. I was lazy and did not leave to run until just before it got dark. I averaged right around 8:00 pace for the first 5 miles, but as soon as it got dark I immediately slowed down a fair amount because I didn't want to slip on ice on the road. I estimate that my HR averaged 135 at 8:00 pace, and about 131 at 8:30 pace. Still a little higher than previously, but more normal. I am starting to check humidity levels to see if higher humidity leads to lower HR. Today, humidity was above 70%.
