I don't know if it is officially considered an extreme sport, but each event would appear to bring about injury, if not death. I don't know what the parameters are for something to be classified as an extreme sport but, if lack of safety equipment, insanity of participants and quantity of injuries are a guide, then it's definitely up there!
