On our Sunday rides we typically do 50-55 miles and girls are no joke. All average 22 mph after riding another 50 miles day before. I have stopped believing in the whole man/woman or young/old thing long time ago. Same group, a guy just rolled over 72 years old, and keeps up with the girls and the boys. As mentioned above as well, I did speak to a nice lady who also mentioned how she is annoyed with guys getting their egos crushed. She said it came to the point that it started with name calling and such, just taking it to a low level. Just like cars, I live by the motto of don't brag how fast you are, there is always somebody faster than you.
