Running Notes by HJL

…especially when I already feel like I can’t breathe properly. What are they thinking?

This morning I headed to the gym for a 60+ minute easy run. I’m still not breathing properly, although I noticed that things got better after about 45 minutes, which is encouraging, if weird.

My heart rate monitor strap seems to need new batteries. When the batteries are low, it starts throwing out readings that are usually fractional multiples of the actual heart rate, such as 1/2, 1/3, or sometimes 3/2 or 4/3, or 60 (presumably from AC line interference). It can also read randomly high, such as the 172 I saw today while warming up (my observed HRmax is something like 180).

Ended up doing about 8 miles at 9:30 pace, mostly at around HR 140-145. This is 15-20 points higher than where I would normally expect to be (120’s) at this pace.
