Girl group Billlie (Siyoon, Sheon, Tsuki, Moon Sua, Haram, Suhyeon, Haruna) performed a celebratory 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 Madang in Yeouido Park, Seoul.

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

Around 7,000 runners participated in this year's race. Various celebrities and sports stars attended to add glamour to the event, with broadcaster Noh Hong-chul, the 'unchanging fixed MC,' serving as host. New Balance women's muse Kim Yuna also attended to cheer on the runners.

After the race concluded, an after-party concert added a memorable finish to the event. Singer George opened the show, Billlie took over the baton to amplify the excitement, and rapper Loco brought the finale to a close.
