of course whitney will take longer including downhill. downhill is not hard, but tedious.
Okay, okay.....now you have me going here. "downhill is not hard"!!!!!! (Hope you know that I'm just playing a bit here, but...)
I'm one of the people who hates downhill. I always felt more comfortable going uphill in training, not so much in a real marathon. But, going down Whitney, though not that bad, still is a bit hard.
