No, I am slower than all of you! I ran on the treadmill again today. This time I decided to concentrate on more intervals of continuous running at a lower speed, rather than trying to get to my goal of a ten minute mile. I warmed up fully for 5 min. and then did 30 minutes, mostly at 5.2 and 5.5 mph, with some 5.8. But, I still had to take some rest, walking for a minute or two 3 times.
I stopped wearing my HR monitor for riding because I was paying more attention to it than riding; what I know about my HR is that it's always high compared to others, although my resting HR in the AM is 55. At the end of my run, I did a little sprint for 30 seconds and I used the HR monitor that's built in. I they they are notoriously unreliable, but my HR was 168. At my age, that means I should be dead! I felt stressed and working hard, but not gasping for breath. For a non trained person 80% of max at my age is about 134. That seems really low to me. When I ride, I would bet my HR is around 130-140, except when I'm climbing. It's kind of discouraging. After a five minute cool down, it was at 120 and I felt OK, but tired.
