Probably not a good thing that your heart is pounding at 16 or 17 on top of riding long distance. Seems more like a medical emergency or at least a waste of energy to get so super hyped up and screaming things at each other. If cyclists did that in real life they would be worn out from just screaming out attack names all the time.
I can just see Lance Armstrong screaming out "Erythropoietin Doping Attack GOOOOO!"
(had to look that one up.)
