Mt Whitney Zone Forums General Discussion sunrise at summit timing?

I left at Trail camp at 0400 on the 16th. Sun was rising when I hit trail crest. Summited at 0730. So, 3 and a half hours for me to reach the summit. I'm about 40 pounds overweight and went pretty slow and steady... So, for me it would probably have worked out to start at 0230 from trail camp. From Whitney Portal in a day... wouldn't be possible for me personally.
