Chilly! Didn't check the forecast well enough, and failed to notice the temperature would take a dip after noon. I felt sporadic snowflakes. It is always harder to get out the door into the cold, but the runs are much better. My HR was lower for a given power, confirming again that HR responds to more than just exercise intensity. When heat disappears from the equation, my heart slows down. I wonder if it feels this dramatic for everyone. I also wonder if there's any major benefit to working in the cold. Like, is my heart actually working less on days like this, or does it compensate for low bpm with higher stroke volume? I gotta imagine it's at least a little easier in the cold. My HR stays at a lower % of max (assuming similar max HR in cold and hot weather). Well I like the feeling.
