Purpose of the Article
In a world where code meets consciousness and bolts mimic bones, the line between man and machine begins to blur. This article captures a defining moment in robotics history—the first time humanoid robots competed in a half-marathon alongside humans.
As the metal feet of machines echoed through Beijing’s streets, a new story unfolded—not of winning or losing, but of dreaming beyond limits. This is more than a race. It’s a portrait of progress, the poetry of persistence, and the promise of partnership between human creators and their crafted kin.
A Landmark Event in Robotics History
The 2025 humanoid half-marathon in Beijing wasn’t just a sporting event—it was a glimpse into the future of intelligent machines walking among us. Held in the Yizhuang district, the event saw 21 robots from top Chinese developers participate in a dedicated 21.1 km race.
Key Highlights:
• Date & Venue: April 19, 2025, Yizhuang Intelligent Connected Vehicle Town, Beijing
• Participants: 12,000+ human runners; 21 humanoid robots
• Significance: First-ever humanoid robot half-marathon run parallel to a human race
• Finishers: Only 6 robots completed the full race
• Winning Robot: Tiangong Ultra (Beijing Humanoid Robot Innovation Centre) – finished in 2h 40m 42s

Meet the Mechanical Marathoners
Before we admire their performance, let’s meet the standout stars of the track—robots with names, personalities, and code-written determination.
Tiangong Ultra – The Iron Victor
Developed by the Beijing Humanoid Robot Innovation Center, Tiangong Ultra stood tall at 1.8 meters and weighed 52 kg. Its name translates to “Heavenly Palace,” a nod to its high ambition.
• Special Features:
• Long-legged design for efficient strides
• Advanced heat-dissipation system to prevent overheating
• Real-time AI calibration during the race
• Performance: Won the robot race in 2h 40m, completing three pit-stop battery swaps
• Fun Fact: Tiangong previously took 8 hours to complete a similar course in January—an incredible leap forward.
Noetix N2 – The Humble Sprinter
From Noetix Robotics, this 1.2-meter, 29 kg robot was smaller but tenacious.
• Highlights:
• Equipped with “training shoes” for better grip
• Focused on lightweight agility
• Finished second among robots in 3h 37m
DroidUp X02 – The Fighter
Representing DroidUp, this robot’s hands were covered in padded gloves—an odd but ingenious touch.
• Notable Traits:
• Modular limb system for quick repairs
• Suffered a near fall but recovered with duct-tape help
• Finished third among robots in 4h 50m
Unitree G2 – The Underdog
Though Unitree Robotics didn’t officially participate, a modified G2 model was fielded by an independent team.
• What Happened?
• Fell at the starting gun
• Became a viral sensation online for its dramatic tumble

Human vs. Humanoid: The Marathon Gap
Despite the excitement, the performance gap between humans and humanoids remains substantial. The first-place human finished in just over 1 hour. Tiangong Ultra lagged nearly 1 hour and 40 minutes behind.
Why the Gap?
• Balance & Coordination: Many robots stumbled due to uneven terrain and changes in gradient.
• Battery Life: Frequent power swaps highlight the limits of current mobile energy tech.
• Heat Management: Overheating motors required cooling stations along the route.
• AI Limitations: Robots struggled with adaptive decision-making on-the-fly.
“We are getting close to reliable mechanical legs, but not yet close to intelligent, dynamic decision-making.”
— Prof. Zhang Wei, Robotics Department, Tsinghua University
The Pit Stops of the Future
A major feature of this race was the concept of robot pit stops, where handlers intervened to change batteries, repair joints, and clean sensors.
Insights:
• On average, robots needed 2–3 battery swaps
• Some wore cooling vests between laps
• Handlers were allowed to assist but not carry or steer the robots
This mirrors motorsports, where endurance is as much about strategic maintenance as speed.
Why China Led This Revolution
China has become a central hub for humanoid robotics, thanks to deep investments, rapid prototyping, and centralized innovation parks.
Robotics Landscape in China:
• 56% of top 100 global robotics companies are now Chinese (World Robotics Report, 2024)
• Government-backed platforms like X-Humanoid aim to industrialize humanoids for delivery, manufacturing, and elder care
• Tech giants like UBTech, Xiaomi, and Baidu are funding humanoid R&D aggressively
This race was not just a display—it was a diplomatic and economic statement.

Humans Cheered, Robots Tumbled, and the Internet Loved It
Spectators along the course cheered both humans and their robotic counterparts. Some robots bowed to the crowd; others simply froze.
Public Response:
• Social media exploded with memes and emotional commentary
• Schoolchildren were seen hugging exhausted robots post-race
• CCTV and CGTN live-streamed the entire race, generating over 20 million views in 48 hours
This whimsical mix of humor, awe, and curiosity made the event unforgettable.
Research Insights and Future Directions
So, what did this race really teach us? Here’s a quick breakdown:
Key Takeaways:
• Mechanical Robustness: Humanoid locomotion is improving rapidly—six finishers is a huge leap from 2023’s 5K tests.
• AI Gaps Remain: Navigation and reactive decision-making need major upgrades.
• Public Engagement Works: Such events humanize robots and inspire future engineers.
• Battery Tech is a Bottleneck: Without more energy-dense solutions, robots can’t go mainstream in mobile roles.
• Global Benchmarking: China is setting the standard in mass-deployable humanoids.
“Robots can now walk with us. Soon, they may run alongside us in life—not to replace us, but to remind us what we’re capable of creating.”
— Lin Yujing, Lead Researcher, DroidUp Roboti
