Turtles, Running

How does a turtle run? Easier shown than told. From hatchling sprints to a grown-up's march.

So — are turtles actually fast?

Tortoises typically walk at around 0.2–0.5 km/h. But Bertie, a leopard tortoise and Guinness World Record holder, clocked 0.28 meters per second — roughly 1 km/h — to become the fastest tortoise on record.

In the water it's another story: sea turtles cruise slowly but are said to hit bursts of around 30 km/h when startled. The tortoise-and-hare race may simply have been held on the wrong surface.
