Most people don't sustain decent speed when being chased by a bear. I bet most (that decide to run) will run while panicking and be out of breath in 5 mins. Also, best distance runners are for healthy people. Humans with idle life and unhealthy lifestyle won't carry the touch.

Out of curiosity I looked up how long a bear can sustain their burst speed.  It’s only a few seconds.  They are ambushers.  They get near their “prey” and rush.  If you can juke them you might, I said MIGHT, have a chance.  

I am in no way on team out run a bear.  I’m just saying if you could make 1-2 strategic direction changes putting some kind of obstacle in between you and the bear you might have a chance.
