It's not any different than most group runs. Starts out easy then someone starts feeling good and decides to up the pace and folks either respond or drop off. There is always the guy that turns every hill into challenge. Let's not forget the guy that likes to finish "strong" and drops a sub-5 mile on everyone or, worse, needs to finish the marathon training group Sunday run with a wicked kick after two plus hours of plodding.
Take away the bikes and lycra and a there is no difference between runners and cyclists. It's largely a bunch of insecure skinny guys trying to prove to the world that they are superior to all of their fellow skinny, awkward, uncoordinated guys in a routine insecure pecker-measuring contest to see who is king of the high-anxiety dorks.
Fixed.
The chief difference, as was already pointed out, is that far too many cyclists are those who proved too fragile to keep up in running.
