Most people are surprised to learn that elephants can outrun a sprinting human. Despite weighing up to 13,000 pounds and moving on legs that resemble stone pillars, an African elephant can hit 25 miles per hour (40 km/h) at top speed — fast enough to close ground on a fleeing threat in seconds. Their speed is a reminder that size and agility are not opposites, and that evolution has found ways to make even the largest land animal on Earth surprisingly quick when the situation demands it.
