Mostly, it turns out. If you have this sense that winds work against you more than they help, you are correct. This graph is taken from Jobst Brandt’s article about wind and cycling. Notice how even a wind from the side slows you down and makes you work harder, and tailwinds don’t help as much as headwinds cost. (Wind speed shown as a percent of rider speed in still air)
