Humanoid robots lose to humans in historic half-marathon in Beijing

On April 19, 2025, humanoid robots and human runners participated in a historic half-marathon in Beijing, China. The event marked a significant milestone as it was the first time that robots raced alongside human contestants, showcasing advances in robotics technology. More than 20 two-legged robots designed by various teams navigated the 21.1-kilometer (13.1-mile) course, which was supported by teams of human engineers and operators. The course was specifically designed to accommodate the robots, with safety measures including a separate lane to ensure the well-being of all participants. Despite their technological prowess, the robot competitors faced numerous challenges during the race, including the need for battery swaps and the occasional requirement for human assistance to keep them upright when they fell. The Sky Project Ultra, also known as Tiangong Ultra, finished the race in 2 hours, 40 minutes, and 42 seconds, which was significantly slower than the human winner's time of 1 hour and 2 minutes. The winning team chief emphasized that while the robots did not win, they demonstrated significant potential compared to Western models, highlighting the competitive nature of robotic innovation. The event was more than just a race; it underscored China’s ambition to be a leader in humanoid technology amidst growing interest in robotics globally. In recent years, China's Ministry of Industry and Information Technology has identified the humanoid robotics industry as a new frontier for technological advancement. The race attracted significant attention, revealing ongoing difficulties in making robots suitable for endurance events like marathons and how human engineers are still needed to assist these machines. Innovative awards for robots included recognition for Best Endurance, Best Gait Design, and Most Innovative Form, emphasizing not only speed but also the evolving standards of robotic performance. As robots like Tiangong Ultra gain increased capabilities, the industry is expected to seek breakthroughs in endurance, heat management, and movement algorithms consistent with their competitive goals. Overall, the event suggests that, while robots are advancing, humans are still leading in long-distance running, beguiling the spectators with the continuing dominance of human athleticism.
