What is the fastest land animal?

The story behind the answer

Cheetah is correct: it’s the fastest land animal, reaching about 60–70 mph (97–113 km/h) in short bursts and accelerating from 0–60 mph in around 3 seconds. Its body is built for speed—light frame, long legs, a super-flexible spine for huge strides, oversized nasal passages for rapid oxygen intake, semi-retractable claws that grip like track spikes, and a long tail that works as a rudder for balance during sharp turns.

Context helps: the pronghorn antelope is second-fastest (around 55 mph) and can sustain high speeds longer, while lions and Thomson’s gazelles are quick but slower. To remember, think “Cheetah = Champion of speed,” and picture those “cleat-like” claws powering a sprint that lasts only 20–30 seconds before overheating.
