"The size and weight of a T. rex would have prevented it from moving faster than 20km/h (12mph), research suggests.

University of Manchester scientists used a new computer simulation to assess the speed of the massive biped.

Based on T. rex's muscles alone, the model came up with a maximum speed of 30km/h, but this dropped to 20km/h when skeletal strength was assessed too.

Had it moved from a brisk walk to a sprint, the dinosaur's legs would have snapped under the weight of its body…"

So, it snuck up on its prey?

It is also theorized that they were pack hunters. You don't necessarily need to run fast if you hunt in packs, a brisk walk would do.

It could outrun most people!

Just want to point out its walk was faster than many people can run, and it was built to sustain speed over a distance. So, unless you're an endurance runner, you're going to be T. rex chow.

The only way to scape from them maybe swimming…

One of the theories is that it was a family pack hunter. The young are more set up for speed. The thought was that the juveniles ran down and cornered the prey until the adults could arrive and finish the job.

I doubt this is a workable thing.

I've never assumed that the Tyrannosaurs were overly fast predators, but capable of a relatively short burst of speed while being able to have a higher endurance to maintain pace to keep the prey moving…
