RRR - Early morning running can indeed be advantageous. With my current schedule, it would be too early for me.
I have a single speed—good choice. I have not ridden it in yeras, though. My area is not conducive to biking, or at least to convenient biking.
Allen - Yes—what a difference a few hundred miles makes. I am concerned about today’s morning run, at it will be getting into the 80s quickly, and with the hills (and southerly breeze) that is the worst of all scenarios. Need to get out there soon...but I also needed some extra sleep this morning.
