• Here, Miranda Lambert joins Luke Combs to sing about a breakup. It's been two weeks since their split and neither can erase each other from their minds. No matter how much distance they put between them, there's no escape from their respective memories.
• The soulful song is a co-write between Combs and Lambert. When they got together to pen a tune at Lambert's manager's office, they didn't have a duet in mind and didn't plan on doing something for one of their albums. Instead, they just set out to write something good that somebody might like.
  
  Combs decided to record the song for Growin' Up. When he went to cut the track, it occurred to him "Outrunnin' Your Memory" would work well as a duet, and Lambert would be a great partner. "So, she came and gave it a run and it sounded great," he told Taste of Country Nights' Evan Paul. "I was really thankful that happened because I think it turned out awesome."
• The day before their session, Combs and his co-writer Dan Isbell penned a song for another artist. "We had come up with this idea called 'When It Rains in Seattle,' which was going like, 'I'll only miss you when it rains in Seattle, which is all the time,'" he recalled to Billboard. "We really thought this person was going to be like, 'Yes!,' but they weren't into it."
  
  The next day, as Lambert and Combs discussed ideas, he brought up the theme of "When It Rains in Seattle." Lambert loved the concept, so they began working on a song based on that idea and asked Isbell to come over to help. "By the time he got there, we had the chorus for this song, which was a completely different song," Combs said. "So we ended up not even writing the 'When It Rains in Seattle' thing."
• Prior to their songwriting session, Combs and Lambert had never met apart from in passing. The pair got on so well they became friends outside of music, and they started meeting up socially with their spouses.
• "Outrunnin' Your Memory" is the only collaboration on Growin' Up and Combs' fourth in total. It follows songs with Eric Church ("Does to Me") and Brooks & Dunn ("1, 2 Many") on his 2019 album, What You See Is What You Get; plus with Amanda Shires ("Without You") on the What You See Is What You Get deluxe version.
