Proper VO2 workout inside HR or Power?

t might make me a wimp but I don’t ride when it’s 20 or 25 degrees with howling north winds. 32 is about my limit because a 32 degree air temp at my house means the low lying areas will be in the low 20s. That’s plenty cold. If I go when its 25 the low lying spots will be in the teens and its just miserable.

This is obviously Fahrenheit?

Yes Fahrenheit.
