Great point about "hiking Whitney and running a race" in a marathon.I personally don't think I could ever run a marathon due to knees and back. That is why I took to running stadium stairs for my workouts. That didn't hurt either. I have had "runner" friends join me and die on the stairs and get incredibly sore.That being said I can hike Whitney and not be affected by AMS while some marothoners might get AMS and not make the summit.
The question is which is harder and the answer should be for who?
