One possibility, to allow for future genetic engineering, doping, bionics and whatever else.

Enhanced Olympics for Superior Athletes
The International Olympic Committee has announced that beginning in the 2008 games there will be two separate classes of competition.
Committee spokesman Kane Neuman explained the new development in the international games with an ancient history.
"We have been fooling ourself for too long, trying to catch athletes who use technology to cheat the games," Neuman said. "We were wrong. We should embrace it and put those people together on a level playing field to compete against each other, while also recognizing athletes who wish to use natural training methods."
"The Natural Olympic Games will be for athletes who do not use drugs, hormones, surgery or genetic alteration to improve their performance. It is the Olympic Games of your grandfather, his father and all those going back to classical times."
"Recognizing modern trends, the Enhanced Olympic Games will allow for any technological advance, and even encourage its promotion. We expect competitors to be genetically enhanced, perhaps use pharmaceutical products and even bring cybernetic augmentation into the competition to show us the best that technology can provide us."
Each class of Olympic competition will maintain its own separate records and issue separate medals and awards.
It is expected that this trend in athletics will expand in the sports world. The Tour de France organizers have also expressed interest in two similar classes of competition.
