Same the 1.94 miles route again. Time, 21:38, about 1 1/2 minutes faster than before. Ran the whole way this time, didn’t stop to walk. Looking at my heart rate monitor, it looks like my heart likes to stay below 180, anything higher and I start gasping for air fast. 180 still seems kinda high, I’ll have to run a hill to see what my true max heart rate is.
