When in doubt, refer the offending rider to The Rules:
Rule #38
Don’t Play Leap Frog.
Train Properly: if you get passed by someone, it is nothing personal, just accept that on the day/effort/ride they were stronger than you. If you can’t deal, work harder. But don’t go playing leap frog to get in front only to be taken over again (multiple times) because you can’t keep up the pace. Especially don’t do this just because the person overtaking you is a woman. Seriously. Get over it.
