I don't know about all of these claims of riding in 30mph+ winds. Riding into a 20mph headwind at 15mph requires >300watts. 30mph headwind requires >500watts for 15mph. If you can sustain that you a quite the cyclist. 20mph is about where I cut things off unless the direction is such that I don't have to ride head into it much. The struggle for me has been day after day of 15mph winds from the sea breeze in the afternoon when I ride, by the time you get to your fourth day of this it is not much fun.
