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

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

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

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