I was having a debate with my friend on the definition of "Sport Climbing". We both agree it means rock climbing with no pre-setup ropes on a bolted route.
I think regardless of whether this route is in an indoor gym or at a real rock outdoors it's all called sport climbing. However, my friend thinks it's only called sport climbing if it's at a real rock outdoors. He called it "indoor lead climbing" if it's in an indoor gym. But I think lead climbing has a broader meaning, it includes both sport climbing and trad climbing and it's also mentioned in this question:
Am I correct?
