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

With powerful performances and commanding stage presence, Billlie has been active not only in their main career but also across various festivals, university celebrations, and entertainment shows. In November, they are set to hold a fan concert to celebrate the 5th anniversary of their debut.

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

After the race concluded, an after-concert followed to cap off the event. Following singer George's opening performance, the girl group Billlie took the baton to amp up the excitement, and rapper Loco brought the finale to a close.
