Winter is approaching in the Northern Hemisphere - so . . .
Given:
- No or little wind
- Clear sky, no precipitation
- 10+ mile ride
- Level or near level
- Daylight
- Average speed 12+ mph
Or as many of these as your riding situation fits. (And, I am sure I forgot something above, which someone will kindly point out to me. )
So, what is the coldest temperature Fahrenheit you will ride in?
And, what secrets do you have about staying warm???
