On April 19, 2025, Beijing made history by hosting the world’s first humanoid robot half marathon, a groundbreaking event that saw 21 bipedal robots compete alongside thousands of human runners in the Yizhuang district. This 21-kilometer race was not just a test of endurance but a showcase of China’s advancements in robotics and artificial intelligence.

The participating robots, developed by Chinese companies such as DroidVP, Noetix Robotics, and the Beijing Innovation Center of Human Robotics, varied in height from 75 cm to 180 cm. Some featured lifelike appearances, complete with feminine features and the ability to wink and smile . While some robots operated autonomously, others were remotely controlled, and all were accompanied by human trainers who provided assistance when needed.

The standout performer of the event was Tiangong Ultra, developed by the Beijing Innovation Center of Human Robotics. Standing at 1.8 meters tall and weighing 55 kilograms, Tiangong Ultra completed the race in 2 hours and 40 minutes, thanks to its advanced running algorithm and efficient battery management, requiring only three battery changes during the race . Despite this impressive feat, human runners still outpaced their robotic counterparts, with the men’s winner finishing in just over an hour .

Not all robots fared as well. One robot collapsed moments after the starting gun and lay motionless for minutes before regaining its footing, while another crashed into a barrier shortly after starting, causing its handler to fall . These incidents highlighted the challenges that remain in developing robots capable of navigating complex, real-world environments.

The event was held in Beijing’s E-Town, a state-backed hub for high-tech manufacturing, underscoring China’s ambition to lead in AI and robotics. Officials likened the race to a motorsport event, given the technical support required for each robot . While some experts, like Alan Fern of Oregon State University, questioned the practical implications of the race for industrial AI applications, others viewed it as a significant step toward integrating humanoid robots into everyday life .

As spectators watched robots donning running shoes, boxing gloves, and headbands with slogans like “Bound to Win,” the event offered a glimpse into a future where humans and machines coexist and compete. While the robots have a long way to go before matching human athleticism, the half marathon marked a significant milestone in the journey toward more advanced and capable humanoid robots.
