It appears you misread the elevation graph. The 1000 ft elevations on that map are "max" elevations; I started my ride at an elevation of 500ft. and reached the 1000ft mark about 20 miles into my ride. Since it was a sort of out and back route, I had the same elevations on the way back. It's not like I climbed one big wall of 1000ft 3 times starting from sea level. Hope that helps and clarifies. Also in case you are interested here is a complete list of popular climbs in the area:I'm not confused. I posted a question to show me where near NYC/Yonkers there is a 1000' climb. You stated that there are climbs all over and posted a picture of a rock overlook.
The OP posted the elevation of his ride up that road that looked to me to have (3) 1000' climbs, where are those climbs?
It's just that simple, paragraph after paragraph about how I'm not from NYC and I don't understand is unnecessary.

My ride was mostly through Bergen and Rockland counties.
