Tough! I don't have a really long commute (New York City, Manhattan, Battery Park City, up the Hudson River bikepath, across 42nd Street to Lexington Avenue and the Chrysler Building), but the headwinds this morning at about 7:15 were intense. I was riding a couple of gears lower than I usually do, and still working harder than most days, and of course going slower. The upside is that if the wind holds up, I won't have to pedal all the way home.
