I hear ya about the head wind i remember one day trying to make15 or so miles the head wind was so bad even in the small ring I got maybe 3-5 mph one tuff day

another day i had this same ferce wind as a tail wind and was cruising 19 to 20 mph with ease

what i really hate is the days thay we go out into a wind and think we will have a nce ride back then the wind changes and we face it on the way back in too
