This is what I did Saturday.
Started with 1 L of water and 1 L of gatorade. My plan was to get more water at Mirror Lake, but we had issues with our filter. The Water and Gatorade lasted until .5 miles before Trail Camp.
Fixed filter and filled up at Trail Camp (100 0Z bladder plus 24 0z bottle with gatorade powder to be added). I left the 24 oz bottle and some other stuff at the JMT Junction, then picked them up on my way back down.
