THE PACER SERIES is a premium marathon event where participants have the unique opportunity to run side by side with the world-renowned marathoner Mary Keitany.

Rather than just honoring her legacy, this event, held on June 28, 2026, at Cheongju Daecheong Lake area, focuses on the lived experience of running together with the "Queen of New York" amidst the stunning scenery of Daecheong Lake. Under the theme of "Running with a Legend," participants will share the same path and breathe the same air as Keitany, crafting their own finish-line stories alongside a true icon of the sport.

The event emphasizes a "shared rhythm," where runners respect their individual paces while staying in sync with both Keitany and the natural environment, aiming for a true festival of running that is completed through connection rather than solitude. By moving together, participants can directly experience her philosophy of "Slowly, but never stop," finding the strength to overcome their past selves and share a profound sense of achievement. Running alongside a global legend will provide a vivid and unforgettable experience for every runner to push their limits and celebrate their persistence together.
