In a historic fusion of cutting-edge technology and athletic endurance, the world's first humanoid robot half-marathon concluded today in Beijing's Economic-Technological Development Area, where 20 robots and thousands of humans challenged themselves on a 21.0975-km course.

The standout robot performer "Tiangong Ultra", developed by Beijing Humanoid Robot Innovation Center, which crossed the finish line in two hours, 40 minutes, and 42 seconds, won the first place.

Designed for marathon-level endurance, the robot boasted a peak speed of 12 km/h and an average pace of 7.88 km/h. Standing 1.8 meters tall, it features large strides, optimized joint torque and human motion data integration to achieve a more natural running gait.

A robot developed by a Beijing-based company Noetix Robotics, won the second place with the result of three hours, 27 minutes, and 50 seconds. The team changed robot player once during the race.
