Taylor Swift is in the middle of her most expensive andextensive world tour yet, paying homage to her 10-album discography on the Eras Tour.

There are 152 shows across five continents, featuring 10 albums and more than 44 songs. Each performance takes at least three hours, and the whole thing will have stretched out over two years by the time she's done.

It's a massive undertaking and a production of epic proportions.

There are nonstop costume changes, large-scale set swaps and stunts that are reminiscent of a Las Vegas residency.

Oh, and it's estimated to have around a $157 million budget.

Watch Taylor Swift announce her new album at the 2024 Grammy Awards. Post continues after video.

The best part? It's not even close to being over. Nope, The Eras Tour has three more shows in Singapore before Swift takes a small break and starts back up again on May 9 in Paris, France (she has 62 more arena performances, BTW).

So with all ofTHATgoing on, we wanted to know more about what happens behind the scenes on the tour, from the impressive sets to the challenging choreography routines.

How Taylor Swift avoids getting sick on the Eras Tour.

It might have been a goal for many Aussies to meet the singer but millions of people were left disappointed because Swift's team makes it impossible for fans to get to her.

It's not just a safety issue, but a health one too.

"When Taylor is on tour, strict measures are put into place to stop her interacting with anyone outside of her 'bubble,'" a source told Yahoo Lifestyle.

"They can not risk her getting sick under any circumstances. Even those in her bubble, including her dancers and managers, are restricted to what they can do and where they can go during their downtime.

"Going on a world tour may sound exciting, but the reality of it is each day just consists of going from a hotel room to the venue and repeat."

They don't just keep this measure in place to protect Swift's health but also to avoid messing up her schedule. The source claimed cancelling or postponing a tour date could cost millions of dollars.

The team is so strict on the singer not getting sick that during her show at the Melbourne Cricket Ground, her publicist Tree Paine was seen walking through the venue with a mask to reduce her chance of getting ill and passing it on to the singer.

Swift is currently on tour in Singapore and fans have alleged she is unwell after there were clips of her coughing on stage, making the strict measure understandable.

In a video going viral on TikTok, she was filmed coughing and clearing her throat as she sang her 'Delicate' for fans at the city’s National Stadium, which holds 55,000 people at capacity.

Thankfully, it looks like Swift will get a well-deserved break after wrapping up 84 shows in 11 months. The Singapore leg of the Eras Tour wraps up on March 9. She won't be back on stage until May 9 in Paris.

Taylor Swift would rehearse on a treadmill.

If you thought a performance like Swift's comes easy, you'd be wrong. The singer, whose concerts run 3.5 hours, prepares for it with some serious cardio.

Swift shared that her training begins six months prior to the tour's first show, per Today .

"Every day I would run on the treadmill, singing the entire set list out loud," she told Time. "Fast for fast songs, and a jog or a fast walk for slow songs."

She also worked with the notoriously exclusive New York City gym Dogpound, where she says there was a strength-training program.

Oh wait, but there ismore.

"I had three months of dance training because I wanted to get it in my bones," she explained. "I wanted to be so over-rehearsed that I could be silly with the fans, and not lose my train of thought."

Aaron Dessner, co-writer on Swift'sFolkloreandEvermorealbums, spoke about just how fit the singer needs to be to perform for as long and as hard as she does.

"She makes it look easy but it's really a feat of incredible endurance," he told People.

"It's hard to think of an example of someone who matches that kind of output, except maybe Bruce Springsteen, but he doesn't have to cover as much ground as Taylor does up there."

She stopped drinking too.

"I was really disciplined about drinking," she told TIME .

"I stopped drinking for a couple months before the show except for on Grammy night, which was hilarious. I gave myself a fun night for that one."

Then she went right back to being sober for the rest of the tour.

"Doing that show with a hangover, I don't want to know that world."

The singer takes recoveryveryseriously.

To make sure her body is in peak condition between shows, Swift gives herself one day to fully rest.

"I do not leave my bed except to get food and take it back to my bed and eat it there," she shared with TIME ."I can barely speak because I've been singing for three hours straight... It's a dream scenario."

Swift continued: "I can barely speak because I’ve been singing for three shows straight. Every time I take a step my feet go crunch, crunch, crunch from dancing in heels. But it’s the most fulfilled I’ve ever felt."

She also said she will perform, no matter how she feels.

"That's part of my identity as a human being now. If someone buys a ticket to my show, I'm going to play it unless we have some sort of force majeure."

Taylor Swift broke a record during her first night of the Eras Tour.

On the first night of Swift's Eras Tour on March 17, 2023, in Glendale, Arizona, 69,000 fans showed up. It broke the record for the most-attended concert by a female artist in the United States, a title only previously held by Madonna.

She then broke it again when she performed to a crowd of 96,000 at the Melbourne Cricket Ground for three nights from February 16-18.

Taylor Swift fans caused a small earthquake.

During her tour in Seattle, Swifties triggered a "2.3 magnitude earthquake", as reported by seismologist Jackie Caplan-Auerbach.

The seismic event happened at Swift's second Seattle show on July 23, 2023.

It's not the first time something like this has happened. In 2011, Seattle Seahawks fans erupted after there was a touchdown by running back Marshawn Lynch. The celebration was detected on the same local seismometer as the Swift concert, Caplan-Auerbach told CNN.

Taylor Swift's parents decorated her guitar.

Swift's parents, Andrea and Scott Swift, decorated the guitar she plays in theFearlesssegment of the concert. They used "super glue and a free afternoon", as the singer described it on Instagram.

The guitar is covered in silver rhinestones, mirroring the one she used in the Fearless Tour back in 2009.

Taylor Swift's blue version of the 'Enchanted' dress took 2,100 hours to make.

Swift wore the blue 'Enchanted' ball gown for the last stop of the Eras Tour in LA, where she announced the release of1989 (Taylor's Version).

Nicole + Felicia, the designers behind the dress, created this as their third gown for the tour, and it took about "2,100 hours to complete", according to the brand.

Taylor Swift donates to a food bank in each city she performs in.

Food banks across the United States and now in Melbourne have reported receiving generous donations from the singer when she performed in their city.

According to reports, Swift has been quietly giving money to local hunger relief organisations when she travels to their city on tour.

Foodbank Victoria, which helps feed those in need, thanked the singer on X (formerly Twitter) on Friday, February 16.

"As if we couldn’t love you any more than we already do," the organisation wrote.

"Your generous donation to Foodbank Victoria will put a sparkle back in the eyes of so many Victorians doing it tough right now! THANK YOU."

The exact amount of the donation has been kept private.

Taylor Swift reportedly receives a special ride to the concert.

Fans have claimed that Taylor discreetly travels from backstage to behind the stage riding inside a janitor's cart so she doesn't get noticed by the audience!

This seems to take place when the pre-show playlist starts playing 'Applause' by Lady Gaga.

It takes 90 trucks to construct the stage for The Eras Tour.

According to Billboard ,the magical set build of The Eras Tour takes an estimated 90 trucks to construct.
