On April 19, 2025, Beijing was the stage for an unprecedented sporting and technological experiment: for the first time in history, 21 humanoid robots competed in parallel with more than 12,000 human runners over a distance of 21.1 km. The goal was not to defeat the flesh-and-blood athletes, but to demonstrate how far robotics has come in speed, endurance, and autonomy, and to raise questions about our shared future with machines.
To ensure safety and flow, robots and humans ran in separate lanes and under different regulations: the robots could perform battery swaps in 'pit stops' and had a team of engineers ready to intervene in case of failure. Along the route, several humanoids tripped, stopped, or required assistance, but the Sky Project Ultra model (also called Tiangong Ultra) emerged as the star by crossing the finish line in 2 h 40 min 42 s. This performance, though far below the human record of 56 min 42 s, marks a significant improvement from its last participation, where it took more than eight hours.
Beyond the spectacle, the Beijing humanoid half marathon invites reflection: to what extent will we incorporate robots into our daily activities? This event not only accelerates innovation in AI and mechanics, but also redefines our relationship with technology. If we see them running today, tomorrow they could accompany us in rescue missions, medical assistance, or urban construction. The future is already crossing the starting line.
