I've chicked a few guys, and I've been...well, it's not exactly considered getting chicked if I get beaten by another girl, so we'll say owned by other women.

I hate it when I catch a guy, and he sees there's a girl behind him, speeds up, slows down, I catch him again, he speeds up, slows down, wash, rinse, repeat. Even worse if I actually do pass him, and then he blasts past me at Mach 3, slows down and lets me pass again, passes me again, and that cycle repeats, because now we're leapfrogging each other and having to pass each other on often narrow trails. Either speed up and dust me, or let me pass and then drop back! None of this speed up and slow down nonsense during casual trail rides! (Obvious exception if I'm passing him somewhere that plays to my strengths, and he's passing me somewhere that plays to his strengths).
