> Cheetah robot can run 10.3 km with a 3 kg (465 Whrs) LiPo Battery

> the 33kg robot runs at 22 km/h (6 m/s). The total power consumption from the battery pack was 973 watts and resulted in a total cost of transport of 0.5, which rivals running animals’ at the same scale. The 76% of total energy consumption is attributed to heat loss from the motor, and the 24% is used in mechanical work

Cheetah was the robot built by Ben Katz, which then went on to electrify Boston Dynamics' dog.

Given we've had no major energy density or motor efficiency breakthroughs since 2015, I bet the above still holds. That's a 30 min run at full throttle BTW. So to escape the current killer bots, try to run above a 2h marathon pace for 30 minutes.
