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

Approximately 7,000 runners participated in this year's event, with various celebrities and sports stars in attendance. Broadcaster Noh Hong-cheol, known as the 'timeless fixed MC,' hosted the event, and New Balance women's muse Kim Yuna also attended to cheer on the participants.

Following the race, an after-party concert wrapped up the event in style. After singer George's opening performance, Billlie took the baton and amped up the excitement, with rapper Loco closing out the finale.

On stage, Billlie showcased powerful performances and commanding stage presence. Beyond their main career, Billlie has been active across 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.
