It's the word "gradually" - is it 1780 feet in 10 miles or in 50 miles? Big difference, but "gradually" leads me to believe it is a long distance, shallower climb, which wouldn't favor a pure climber who would excel at the steeper climbs.
Marco Pantani was a pure climber - tiny and wiry and strong. Mario Cipolliini not so much, but Mario could hang with Pantani on the shallower climbs I am sure because the power to weight ratio is not such a factor.
