how fast are road runners

Roadrunners can reach quite impressive speeds for a bird that can also fly. In brief: a Greater Roadrunner can sprint up to about 26 miles per hour (41 km/h), while a Lesser Roadrunner tops out around 20 miles per hour (32 km/h). They’re the fastest-running birds that still retain the ability to fly, though they typically rely on running for speed and evasion rather than sustained flight. If you’d like, I can pull in more detailed sources or compare speeds among related species.
