When you hike do you ever jump down a 20-foot cliff?
It's asinine to get into this dick measuring contest, you shouldn't claim your sport is more hard-core than a sport you don't know. This mentality is why Lance Armstrong got his ass handed to him the first time he tried mountain bike racing because he thought it would be easy. And yes, there are race format where you carry bikes uphill: https://en.wikipedia.org/wiki/Cyclo-cross.
No. I think the OP was referring to road racing. One question, "do you carry the bikes uphill?"
