silly question

A man out waking two tiny dogs asked me, " Is it easier to run uphill or downhill?"

He asked me this as I was running up a 7% grade.

I hope he didn't expect an answer.

I am a good hill runner but yes, uphill is always harder because of Gravity; Downhill can wreck your knees. And usually, there is another hill up ahead.

A good steep hill clears the mind.

So, yes and no, Man with 2 tiny dogs, running uphill is easier and harder.
