Not that hard to do in a large field. One or two minutes of straight out full bore running, in circles, with twists and turns and thewhitetail becomes a different animal. Got to realize they are not designed for that kind of evasion. There is no predator in the world that can run flat out full speed for over a minute or two. Most predators throw in 20-30 seconds and if they ain't caught it, it gets a rain check. The only thing capable ofthat kind of extended exertion is a machine.Same with humans in a fight, 1-2 minutes of full out fighting and then kaput. If you never give the deer a chance to rest after a five minutes of chasing I'd think you'd be able to get off and wrestle them down to the ground by hand. In fact most animals especially if its warm out automatically stop after their bodies begin to overheat too much which is what would occur if they were being chased by an ATV and running at full speed in warm weather.
