Question: How does a kid with 12 in long legs get away from an adult?
Answer: Frequently.
Their real secret is persistence, like a canine running down a deer, they just don't stop unless physically restrained.
Because they don't have a plan or destination, just satisfying the urge to move, their next move is almost impossible to predict. That leaves only reaction so you're playing catch up all the time, especially if you take your eyes off them for 0.001 seconds.
I may be misguided because I've only had to do that for no more than a couple days at a time, and parents/teachers grow eyes in the back of their heads. Regardless, I honestly can't imagine it getting easier. Spend the whole day at the gym? Nonsense, borrow the neighbor's toddler for an hour.
