Yeah, no middle aged dude in good shape can run 27 MPH. No human being, ever, has ever been able to maintain a speed even close to that for miles like Grizzlies can. Including, I might mention, their cubs who were running with their mothers. A grizzly running at 30 MPH is not an outlier like the sprinter you are talking about is.
I never claimed the seasons don't affect a bear's speed. I said that YOUR claim that a grizzly in Autumn can't outrun a middle aged dude was pulled straight out of your ass. Go ahead, back your own claim dummy.
