Fifty years ago, if you’d asked the dinosaur experts, they would have told you that Tyrannosaurus rex was a speed freak – a giant predator that could outrun racehorses. The paleontologists would have pointed to its three-metre hind limbs, leggy for even a big dinosaur, and described the creature as sprinting after prey at speeds of 40 mph (64 kph).
But a better understanding of physics kneecapped the swift T. rex concept. Scientists, rather than looking at the bones alone, began to gauge dinosaur locomotion via models of skeletons and muscles. The picture that came into focus was a slower beast: T. rex, although no less of a predator, was certainly less fleet of foot.
A new report, published Monday in the journal PeerJ, refined just how fast the dino could go. T. rex wasn’t much of a runner, the study authors say. In fact, it couldn’t run at all. Instead, the animal speed-walked.
Thanks to its wide stride, T. rex would reach about 12 mph (19 kph) at its quickest hustle.
Even if T. Rex couldn’t run, he could still speed walk his victims down. THOMAS HUTCHINSON; PROVINCIAL MUSEUM AND ARCHIVES

always loved dinosaurs too...
Even today i can picture Triceratops epic battles with T-Rex
I bet T-rex didn't always win
