I think the Olympics should be changed to a single giant game of human hunting where each country sends in a team that tries to hunt the other teams while also trying to survive. Of course, it would not be a lethal hunt. More of if you get captured or you can't gather enough resources. You could have long distance runners trying to chase down the sprinters and wrestle them. Or the volleyball teams trying to hit you with a ball. Or the cyclists and rowers attempting to reach random supply drop points with out getting captured.
The possibilities are endless and there would actually be real strategy and teamwork (or solo) in addition to boring athletics.
