pcad can actually string together a 10k foot 100 mile ride. I used to do it when I lived in that area, it uses 5 'major' climbs: storm king, bear mt, willow grove road (aka gate hill), greenwood lake, and mount peter. Along the way there are also several .5-1 mile grinders that kick the total up to 10k. I haven't done that loop in probably 15 years, but I rode it pretty regularly way back when.
