Thank you very much for answering my questions. It was helpful. We ended up having a good day as a group and got up and down safely.
I on the other hand struggled. Coming into the hike I was extremely prepared. I've hiked Baldy maybe 15 times and Whitney 3. I have never had any real issues outside of a mild headache above 13K.
Yet this past Sunday I was struggling. I kept trying to fix it with hydration, nutrition, tempo etc. All the tricks that usually work. I suspect I had mild AMS and it started at 7000 ft. Yet these symptoms were different. I had no headache and a good appetite. I just felt extremely heavy and listless. I was out of breath constantly.
In all it was pretty discouraging and I don't look forward to putting myself in that position again.
