Mt Whitney Zone Forums General Discussion whitney day hike food?

A few years back when I did my day hike, I grabbed a footlong subway and ate it at trailside meadow, even though I was not that hungry. I was feeling great UNTIL I STOOD UP. I was nauseated and in a world of hurt until I finally snapped out of it a good way up the switchbacks. I'm fairly sure the heavy meal was at least a short-term disadvantage, but it may have helped the rest of the trip.

For me though, I think water is the biggest concern once you know you have enough snacks to stretch out through the day.
