Since fat people and old people don't have a chance in hell of winning this game and since well-traveled people have a big advantage, why don't they just drop the pretense and make all the teams ones that are capable of winning? Pick teams that are all in awesome shape, can speak multiple languages, and have travel experience. Then give them much tougher physical and mental challenges. Have them spend more time bicycling, hiking, running, swimming, and rowing boats during the legs. Give them some REAL navigational and intellectual challenges. Lets see what the elite can do.
