Comments: HR was low, I thought maybe due to cooler temp but it was still in the 50s, not that cold. Had to stop for a train. Cadence was up, I wonder if because of the muddy run yesterday somehow. Lugging all that mud was a strength workout? Sliding/slipping engaged stabilizers? I do not know. Chased by a doggie! Just ran up behind me. I involuntarily yelled and the dog went away.
