Kinesiologists and mechanical engineers are the who. Ostriches have a radically different body plan than humans, one that’s mechanically much more suited to running fast. Add long, lightweight legs which bend the other way and hence have advantageous leverage and a stride length of 3 to 5 meters. (Usain Bolt has a stride length of less than 2.5 meters, and he’s an outlier among humans.) Even if we genetically engineered a hyper-fast-twitch muscle fiber and springy tendons, those would just tear apart our joints when paired with the body mechanics and locomotion style we’re working with.








Would that be a human with ostrich legs, or an ostrich with a human body? Indeed, there are a lot of philosophical questions, but if we’re allowing technological augmentation, then Todd Reichert is indisputably human and managed 144 kph.
