I did the trusty Hartely single track loops and after the first one, I had all I could do to talk myself into a second loop. (didn't see any other headlamps out there this morning to help motivate me???) Once I made the mental decision to hit the second loop I immediately felt a burst of energy and efficiency in my stride. Crazy how the mind can mess with you.
Happy with this effort in yet another sub zero morning.
