The group Billlie (Moon Sua, Sheon, Tsuki, Siyoon, Haram, Suhyeon, and Haruna) performed a congratulatory stage at the after concert of the New Balance global running competition '2026 Run Your Way Seoul 10K RACE,' held on the morning of the 4th at the Culture Plaza in Yeouido Park, Seoul.

Billlie showcased powerful performances and commanding stage presence. Beyond their main music activities, Billlie has been active in various fields, including festivals, university events, and variety shows, and is set to hold a fan concert in November to commemorate the 5th anniversary of their debut.

Approximately 7,000 runners participated in this competition, and various celebrities and sports stars attended to add glamour to the event. Broadcaster Noh Hong-chul, the unchanging fixed MC, served as the host, and New Balance women's muse Kim Yuna attended to cheer on the athletes.

After the competition concluded, an after concert was held to wrap up the event on a high note. Following singer George's opening performance, girl group Billlie took the baton and heated up the atmosphere, and rapper Loco finished off the finale.
