I've hiked to the top twice, 14 mile round trip from the gate if I recall properly. Mild steep at the start, long and flattish through marmot heaven, then the sad down part before final up part, gets a little steepish at the end. Probably the easiest 14K a person can do, though it can be a long day in the open sun. (got denied once due to snow and wind)
Here I am relaxing before the "sad down part before final up part":
