Run BTS

Run BTS is a South Korean variety web series starring the K-Pop group. Broadcast since 2015, each episode involves the band members taking on games, challenges or secret missions. The boys earn prizes if they succeed or receive punishments if they fail. This fast rap song both references their variety show and looks to their future. "For 'Run BTS' we kept saying we wanted to try doing a song in our older style, so we chose a title that both shares its name with our variety show and reflects who we are—always running," Suga told Weverse magazine. "All the members have come a long way, and there's times when we're exhausted but there's also things we want to do moving forward, so I think we tried to include those desires as well."

"Run BTS" is one of three new tracks the K-Pop group recorded for their anthology collection Proof. The other two are the album's lead single, "Yet To Come (The Most Beautiful Moment)," and a continuation of "Epilogue: Young Forever" titled "For Youth."

Suga's verse gave him an opportunity to show off his rap skills, something he's not had much opportunity to do on recent BTS albums. "It made me think of the past, which made me want to write something a little tighter, but rapping it was really difficult," he said with a laugh. "We got it recorded quickly, but it had been a long time for me, so I really had to work at it when we were recording."
