Hmmmm, I was group riding this weekend and as people fell off the back.. Well, I wasn't the one pushing, I don't see any reason to have people fall off the back in a friendly group ride. Since the reason I would group ride is to make and have some friends. not to spend 70+ miles regretting that you came out as you end up grinding through the wind alone.... I can do that at home.
As people are coming off, I always see it like the heard of Gazelle and the pride of lions in pursuit, the weak ones falling off the back. I shed a small tear, never to see them again.
Maybe I'm not drinking enough.
