Sometime while I was sleeping, someone exchanged my blood for 20W-50 motor oil. I could not get anything going this morning. Every hill was a mountain, every breeze a gale-force wind. I don't use any sort of heart rate monitor during my commute, but it didn't seem like my heart rate was increasing enough to meet the demands of my legs. I'm never at my best in the mornings, so hoping for a more energetic ride home this afternoon. Have a great day, everyone!
