“If you haven’t seen jousting before, picture your worst nightmare come true,” says Luke Campbell, chief operating officer at Epicentre.tv, which is streaming the first World Jousting Championship this weekend on IBM’s live streaming platform. “It’s two guys running on horseback, down a tilt line, 60 kilometers an hour (about 40 miles an hour) using wooden lances with metal tips to knock each other off. It’s insane, actually. You have to witness it to believe it.”
