If you're given $50,000, but have to be chased by one animal for 24 hours, which animal are you choosing?

Champanzees. They stop chasing after you when they get tired and stop. They would keep going, but it's easily no point for them. They give up and go back where they came from.

Or a bear if there's a hill. Just go down a Hill while the bear falls and rolls down the hill.
