Got a new pack, and an important lesson

 Yesterday was a disaster. My bike ride was supposed to be 26 miles long (with a stop halfway to buy a surplus ALICE frame and pack), but I stopped just past 24 and all but collapsed outside a convenience store. Over the course of the next hour, I drank a half gallon of water, and finally slowly pedalled the last bit home. There, I hosed myself off, and promptly threw up. Over the next few hours, I dozed, drank water, and threws up over and over. I finally went to the hospital, where I was diagnosed with acute kidney injury. I spend the next several hours getting saline pumped into me. I was then released; I walked home, buying water and peanuts and beef jerky on the way (I wanted salt so badly), and finally got home around 3 in the morning, whereupon I promptly went to sleep. I felt bad enough this morning that I didn't even stretch. From yesterday morning to the point just before I went to the hospital, I lost 6 and a half pounds; that's nearly a gallon of water.

Ugh.

It's my own fault, obviously. I need to carry and drink a LOT more water on treks that long in the sun. Today, I only biked about ten miles, broken up into chunks. I took the bag off my ALICE frame and figured out a way to lash the folding bike to it; tomorrow, I'll take it on a walk and see how it performs. I'll also make sure to stretch. I've added a bit of bodyweight strength training to the end of my stretching; pushups, then situps, then squats. I started yesterday with 20 of each; I'll increase the number, slowly and carefully, until I reach a number I'm comfortable with. If I'm feeling okay, I'll also make a shopping trip.
