Just not so. On average men are stronger than woman in any town I have lived. But, no mistake, some woman are certainly faster than men including me. I find most woman to be slow riders in fact....16 mph is a pretty typical average for a woman out on a road bike. I pass them everyday. Very rare that a woman ever catches my wheel but men do on occasion, certainly a much higher frequency. I am friends with the fastest lady in my town and ride with her from time to time. I can hold her wheel for a while but after about 30 miles she will wear me down.
