All they have to bring is a suit, goggles and a cap. For the synchronized swimmers, add hair gel and glitter. Throw in a robe or warmup suit and they're good to go.
Same for gymnasts, who need to tote only leotards or pants and shirts. The uneven bars, balance beam, parallel bars and pommel horse will be provided on site.
But for the real horses, who must spend a week in quarantine, traveling isn't so simple.
The process also can be complicated for pole vaulters, who must check their poles, pay extra baggage fees and hope the equipment they love will show up at the other end. That doesn't always happen, especially on trips to out-of-the-way places.
"When you start switching airlines, that's when you start losing poles," said American champion Jenn Stuczynski, who has lost poles but later got them back.
Even the shortest trip requires a mountain of red tape and careful preparation for athletes in shooting sports. Like fencers, shooters can't carry their weapons on board commercial airline flights and must pack them and check them as luggage.
Kim Rhode of El Monte, who won two gold medals and a bronze in double trap shooting and will compete in skeet shooting at Beijing, goes through a tedious routine each time she travels.
She must unload her gun, place it in a packing case, sign a declaration at the check-in counter that it's unloaded, lock it and bring it to Transportation Security Administration agents. They may open the case before it's scanned and loaded into the plane's cargo hold.
"When we get to another country, we pick it up on the other end and we once again have to go through customs and declare it," Rhode said. "And of course there's tons and tons of paperwork we have to fill out prior to doing that. Before we get there, even.
"Basically they check all the serial numbers on the gun. So they have to open it up again, they verify all the serial numbers are correct with all the paperwork that we filled out. They'll usually either stamp it, give us a little piece of paper with a stamp on it or a signature or whatever."
From there, she said, the shooters will take them to a police station or the competition shooting range, where the guns are locked up. Sometimes, police officers will take the guns directly to the shooting facility.
Fencer Jason Rogers of Los Angeles reluctantly checks his saber before plane trips.
"The stuff that we have is actually not really all that scary-looking," he said. "The practice weapons, they're not sharp. They don't really resemble actual swords with which you impale somebody. So that's not really an issue."
The issue is losing everything else. The sabers aren't particular to a user and can be borrowed, but that's not true of all his gear.
"Literally, I'm carrying every article that's truly essential," he said, "like my shoes, my fencing pants, my fencing jacket, the jacket that we wear on top of that. Anything that's going to be difficult to borrow, I carry on. Then you just hope at least a few of our bags show up."
Stuczynski and Rhode have contingency plans in case their bags go astray.
"I have poles at the factory ready to go in case they have to send them out," Stuczynski said. "And I also have a bag that's packed right now and on the pad at home where [her coach's] brother is on call in case he has to ship them somewhere, and he has all the information.
