I started the Whitney Portal trail at 11am. Had to pick up the permit from the Lone Pine Visitor Centre (which opens at 8am), grab a heavy breakfast, get to Whitney Portal through the construction zone and rearrange the backpack. So 11am was the earliest I could manage to start. Reached Trail camp slightly after 4pm with a 20 min break at Outpost for food and water.
The next day, as I mentioned in my post, left Trail camp for the chute at around 815am. Ideally, I would have started earlier if I had stocked up enough water. Was at Trail Crest by 1030am but I was slow on the ridge and only managed to summit by 1pm.
Let me know if you have any other questions. Good luck for your climb!
