52:59/157
This morning I ran about 7 mi. (11.2 km) going over through Pontcharra and back. It was raining and chilly, about 2 degrees (almost 36 Fahrenheit).
This was the first run for which I used the heart monitor. I spent only 31:19 in the training zone, mainly because my average was just one beat per minute lower than the max. of 158 for the zone. According to their calculations, 158 bmp is supposed to be 85% of my maximum.
It's not clear what that means. I am still a little bit ill, but was not running hard. When I noticed I was going off the top end of the zone, I'd slow down. As Hal Higdon writes, these weekend "long" runs -- they vary from only 6 mi. to as far as 20 mi. -- are supposed to be done significantly slower than your race pace. I think he writes something about 60-70% of your max. heart rate.
The Courir en France web site says 157 is in the middle of my résistance douce range. Apparently it's too high for endurance, but they also have a résistance dure range that goes up to about 95% of my theoretical maximum.
If I get a chance this to go back and see Dr. Rantz, I'll ask him about the heart rate range. It would be nice to be able to run 15 km/hr. with a heart rate like I had today.
