Must have been feeling froggy for today's 14.2 km walk. A jumping 8:44 per, but only a moderately light 104 bpm (69%). So the question is, as always: is that a brisk walk? Am I exercising? Does this matter? Am I having an exercistential crisis?
At any rate, it was a nice morning with the temp 18.9C and 73% humidity.
Stay tuned.
