I've been there. At nearly 14k feet it is wear-a-coat cold in the middle of summer on the summit, particularly at sunset (and you really don't want to miss sunset if you make the trek). The air is also very thin. You cannot fly an unpressurized aircraft above that height because of the thin air. FAA regulations require supplemental oxygen to fly above 12,500 feet for more than 30 minutes. Just a short jog uphill will leave you winded, even if you are in really good shape. The visitor's center is at about 9k feet and is much more hospitable.
There is also a notable lack of soil. It is mostly just rocks. Lots and lots of rocks. I really doubt very many people would be running about barefoot on the summit.
