Well, I didn't make it. I think I might have had I not been injured a month and a half ago and forced to halt my training routine, but as it was, my body couldn't handle it. Despite steady hydration and electrolyte intake, my legs started cramping pretty bad at around 17 miles.
Between the heat and exertion, I became exhausted at around 30 miles and even slightly delirious. I started to get pretty bad cold sweats and feel flu-like. I sat down at the end of the next section, at 32.5 miles. After an hour, I still felt extremely sick and my legs hadn't improved. The balls of my feet were also in pretty serious pain since I hadn't been doing enough training recently to keep them "tough". Finally, the tendinitis was just starting to come back, and I didn't want to turn it into a permanent injury.
I was way behind schedule at that point and the last six miles were tough, with 1900 feet of elevation gain, and they had taken me about 3.5 hours. It was apparent that the attempt was blown, so I called it.
I'm frustrated I didn't make it, but my spirits are actually pretty high overall. I knew that this was a possibility, so it is what it is. I still had a great adventure, in both my training and the actual attempt, and I'm in what's by far the best shape of my life as a result of it.
Not sure I'll attempt this or anything like it again as I have a son that'll be here in a month, but I'll definitely keep up the trail running and hiking. It's become a big part of me. Thanks for everyone's help and insight over the last few months!
