Mostly I was referencing just dead air drag, but it’s pretty much the same sort of aero effect with headwinds thrown in except obviously to a greater degree. Last year before retirement I had a day ride planned to see my parents 20 miles away. The day approached and wind forecast was greater. I had it planned, and darn it, I was going to do it. BIG wind on the way back. Easily 25 mph right at me. Strongest winds I ever rode in. Had the miyata triple in 2nd easiest gear on level ground. No coasting as you would come to a dead stop in 25yards. I survived but won’t forget. Stupid I was.
