How long it takes: 2-3 days. That is the figure the permit publishes — this page does not divide the route into days, because no source records which stop you sleep at.
The stops below are the route's published mile markers, in order, with the elevations recorded against each one.
Distance and elevation change on each leg are the difference between the two published figures either side of it, so the legs are arithmetic on the markers and nothing more.
Adding up only the climbs between markers gives 4,042 ft, which is a floor rather than the total: anything that rises and falls between two markers is invisible to it.
