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

Billlie has been showcasing powerful performances and commanding stage presence, remaining active not only in their main career but also across festivals, university events, and variety shows. In November, they plan to hold a fan concert to celebrate the 5th anniversary of their debut.

Around 7,000 runners participated in this year's race, with various celebrities and sports stars attending to add sparkle to the event. Broadcaster Noh Hong-cheol, the event's perennial 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-party concert wrapped up the event on a high note. Following singer George's opening performance, girl group Billlie took the baton to amp up the excitement, and rapper Loco closed out the finale.
