Athletes at the top of their game are ready to take on others at the top of theirs not only on the sports field at the Olympics, but also in the bedroom if reports of promiscuity and heavy partying in the Olympic Village are to be believed.

Smuggled alcohol, drugs and mountains of free condoms give athletes at the games a way to keep themselves occupied, writes the anonymous author (apparently a former British athlete) of the recently published book The Secret Olympian, who claims to have competed in the Games once upon a time.

"What happens in the Village, stays in the Village" has been the unwritten rule that all competing athletes abide by… until now, that is.  Expect an account of the inner workings of the athletes' village - from the tough training regimes and visits by politicians and "their flirty spouses", to the post-Olympic partying in which debauchery of the most frantic kind is had.

Alcohol was once smuggled into the drug and alcohol free zone in past Olympics, but this year it will be available to some extent. USA alone has two sponsored beers halls.

It would seem the author has a point about the crackling sexual energy in the athletes' compounds. This year, 150 000 condoms have been provided. That's 50 000 more than were available at the Beijing Olympics — 15 condoms each to the 10 500 competing athletes.

Past Olympics are no exception either, says the author who gives an account of each Olympics from Munich 1960.

Even those athletes accustomed to more comfort than the single-bed, two-to-a-room life that the Olympics Village offers wouldn't miss it for the world. Spanish Grand Slam specialist Rafael Nadal told Brian Viner of the Daily Telegraph that spending time in the village with the Spanish team was one of his best experiences.

He told Viner that he sees himself as more of a team player, suggesting that time with the team filled this gap where lonely tennis competitions don't. Considering this new reveal-all book, perhaps there's more to Nadal's story, and many other athletes' stories too.

Sex, drugs and rock n roll are all very well, but if you're aiming for a gold medal, celibacy is your best bet, another anonymous source told Viner. "Sex depletes the testosterone level… so athletes who need a bit of anger, a bit of tension, to perform at their best, shouldn't have sex, at least not the night before. If you're laid-back, you can do what you like. But it wasn't for me."

With just a few days to go before the Olympics begins, the book ought to spark the imagination of spectators and may leave a few athletes a little indignant.
