Everyone's will vary some.

My device said 6,409 feet of elevation gain and 11.3 miles from portal to the top, and 239 feet of elevation gain on the way down for a grand total of 6,648 feet over 22.6 miles. Others have had shorter distances recorded I know.

Also of interest, my GPS said the summit was 14,478 feet, but it's similarly a little off on other mountains as well.
