What did I discover? I can probably ride about 25 miles at 6F before I would need to stop somewhere to warm up. Riding home from breakfast the temperature warmed to a balmy 16F. At that temperature with the gear I have I could ride all day.
Now I know. And there is no further need to ride when it's that cold. As I near age 71 I'm less interested in stretching limits. A subject for another day.
I made a video of the ride if you're interested.
