2 hours yesterday on a grey December day. ~45 degrees. And since we are talking about it, I had a long sleeve base layer, ss baselayer, ss jersey, arm warmers and wind jacket with leg warmers. Neoprene booties with wool socks.

I hate being cold but dont mind riding down to about ~35 and sunny. Any colder and I'm probably staying inside unless it is super calm and sunny. The one thing I worry about the most is my feet. Once they get cold im done. Being diabetic, once they start to get cold the only thing im worried about is getting home. Ive never had any issues, but at the same time I don't need to do harm because I wanted to ride bikes.
Coldest ride I did last year it was ~18 when I left the house and maybe warmed up to about 20. I had like 14 layers on.
