Surprisingly, the difference in elevation between the I-95/I-26 split in SC and our upstate NY cottage is exactly the same no matter which route we take! The ups and downs must even out either way somewhere along the way to end up at the same elevation... ;)
Well of course. If you start at sea level and end up at sea level, you didn't climb at all :)
What I meant was the amount of time you spend going uphill at 35 mph is greater than the amount of time you spend coasting downhill at 55-65 mph. This is a classic problem I give to my flying students to get them to think about how a headwind effects a flight.
