Yesterday I day hiked Mt. Langley, which I considered as tough a day hike as Whitney. I kept it simple & packed only foods I knew I like that contained nutrition given the circumstances. Ate two hard boiled eggs & a banana the first three miles or so. Sipped lots of water along the way, then a PB&J sandie. Lots of hard candies all day too. Every hour or so I consumed fruit, veggies or string cheese. At the summit I enjoyed my soggy turkey sandwich & Gatorade. Trail mix, Cliff Bars on the descent.
