You don't need the clones. You just need to be able to stay out of the animals reach. We are the only animals capable of running for days at a time. We're not the fastest, burn motion is very energy conservative.
You could hurry most prey to chase you run away from it and just keep doing it until the prey died of exhaustion. Of course you'd have to be in top physical condition which mean or any of my clones would be but the training will be part of the requirement.
