Robots race against humans in China marathon

In a groundbreaking event, China held recently the world’s first marathon featuring humanoid robots racing alongside human participants.

Leading the pack was the Chinese-made robot Tien Kung Ultra, which completed the 21-kilometer half-marathon in just under 2 hours and 40 minutes — all without showing any signs of fatigue, according to the state-run *Global Times*.

Nearly 20 robotics companies participated, including Unitree (G1), Leju Robotics (Kuavo), and NOETIX (N2). To ensure safety, robots and human runners were separated by barriers, and the robotic participants followed different timing protocols.

The humanoid robots started one at a time, with each launch signaled by a gunshot at one-minute intervals. Along the course, support stations allowed teams to conduct maintenance, including battery replacements and other tune-ups.

To cope with the challenges of long-distance running, some robots were equipped with hot-swappable battery systems and specialized footwear or abrasion-resistant foot attachments.

The event marked a new frontier in robotics and endurance testing, showcasing how far humanoid engineering has come — and hinting at a future where machines might one day match or even exceed human stamina.
