If the idea of robots taking on humans in a road race conjures dystopian images of android athletic supremacy, then fear not, for now at least.

More than 20 two-legged robots competed in the world’s first humanoid half-marathon in China on Saturday, and – though technologically impressive – they were far from outrunning their human masters over the long distance.

Teams from several companies and universities took part in the race, a showcase of China’s advances on humanoid technology as it plays catch-up with the US, which still boasts the more sophisticated models.
