Teams compete in a relay marathon around a 2km course at Premist Dome. Participants can join with colleagues, classmates, or family members. The 2026 edition features three categories: full marathon (42.195km), mini marathon (10km), and a new 5-hour marathon challenge. Teams can range from 1-21 people for the full marathon, while the mini marathon accommodates 1-5 runners, making it accessible for beginners. Costumes are welcome, and the event includes food stalls, entertainment, and prize drawings.
