You are able to do the Skyline Trail faster than I can; so I'll bet you'll be faster than I am on Whitney. It has taken me 8 to 8.5 hours to get up Whitney and then 5 hours to come down; so 13 to 13.5 hours. I think you will be able to do the uphill in 7 hours or less, which will bring you down to 12 hours or under round-trip.
This is just my guess - sometimes it gets to be really slow going up there between trailcrest and the summit if the thin air gets to you.
Tina,
I'll be there at the same time.
I have a multi-day permit starting on the 5th, so our summit day should be the same.
We're camping at the Portal on the 4th, planning on Trail Camp on the 5th; and depending upon how all goes, summiting on the 6th and either heading all the way down - or stopping to rest again at Trail Camp.
