Run at 50F weather and get your lungs acclimated to slightly chilly temps. For me, it takes a week or two to get used to even 50F.
Then, once your lungs are used to that, 40F and 30F are next.
I never went below that this past winter. But lung cold weather training definitely exists. Your body really does adapt if you give it the few weeks it needs.
