Over the course of a little over eight months in 2023, Taylor Swift played 66 sold-out shows across the Americas as part of her history-making Eras Tour. Each night she was up on stage, Swift belted out 40-plus songs while performing hours of intricate choreography and trying to make sure tens of thousands of fans were having the time of their lives.

The first year of the tour, which is set to run for an additional 85 shows in 2024, required intense physical, mental, and emotional forтιтude from Swift, who told TIME in an interview for 2023 Person of the Year that she wanted to “superserve the fans” to repay them for the effort they put in to attend her career-retrospective concert.

“They had to work really hard to get the tickets,” she said. “I wanted to play a show that was longer than they ever thought it would be, because that makes me feel good leaving the stadium.”Once Eras was underway, Swift was often performing three back-to-back shows per city. In Los Angeles, her final U.S. stop of 2023, she did this twice in a row with only a day’s break in between for a total of six shows in seven days. During the hiatus between tour legs, she would spend a “ᴅᴇᴀᴅ day” recovering in order to get ready for the next string of concerts.

“I do not leave my bed except to get food and take it back to my bed and eat it there,” she said. “It’s a dream scenario. 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.”

The Eras Tour will resume in February 2024 for a six-month run across Asia, Australia, and Europe before returning to North America in October for its final 18 shows. And Swift plans to be in top form for all of it.

Before the show started, Swift says she and her team camped out in Glendale. “We actually got to be in the stadium for almost a month running the show several times a week,” she said. “So that was extremely helpful.”
