Kakashi said, "And this would be the major drawback.. Along with all the experience he also ends up reassimilating the mental stress his copies incurred as well" chapter 318, make of that what you will, the clones physical stress is accumulated as mental stress and that is what I meant by exhaustion, did you see anyone exhausted after running for three days nonstop if they have enough chakra, no? what Actionmanrandell is saying is correct chakra is the thing here. It's the Physical and spiritual energy that is governing everyone's strength, lifespan and everything.
