Ah, ye old homo sapien hunter trick

According to the documentary Jurassic Park, a T-Rex can clock in at 35 mph. Plus, in the area of a football field, if you do get any kind of a lead, it can just cut you off when you need to turn.

I was doing some research to see if this is feasible, and found this page with this passage:

(Though 12 miles per hour approaches the top speed of a typical human, depending on conditioning—it equates to a 20-second 100 meter dash or a 5-minute mile—the T. rex’s slow acceleration and inspiring teeth would give the average runner a reasonable chance of outsprinting or outmaneuvering the lumbering predator.)
