I've joked before that the hardest part of hiking is eating Clif Bars. I've had gagging fits trying to get them down haha. The dense texture is rough, but it helps to find the right flavor. You get used to it, too. They're worth their weight in gold when it comes to energy - it's straight up fuel. There's been a couple times where I was totally drained and 15 minutes after eating a bar, I felt brand new. If anyone has the chance, try drinking a Muscle Milk or any other kind of protein drink as soon as you can after a hike. I really think it makes a big difference during the recovery process. Gas stations are always first on my list post-hike so I can drink one.
