Robots ran a half-marathon faster than any human ever has. At a Beijing race, the fastest robot finished in a time that obliterated last year's best robotic performance of two hours and forty minutes.

That year-over-year gap is the real story. Whatever engineering changes happened between these two events compressed an enormous performance deficit in a single iteration cycle. The specific mechanism behind those gains is worth understanding.

The full article breaks down which robots competed, who built them, and the exact winning time that beat the human record. Read it to understand where the hardware and locomotion software actually stand today.
