25.3 miles. 5:32 AM. It was warm this morning. The thermometer in the car showed 80 degrees when I got to the parking lot, and it was about 91 degrees when i got back. There were points on the run that were certainly cooler because of the elevation (9,400 ft), and it was windy most of the time. When I started out it was dark and there was thunder, lightening, and a little rain as a fast moving storm blew through. Great way to start a long run in the mountains. Left from  the Kaysville Wilderness park, near the start of the Wasatch 100. Ran about the first 12.5 miles of the course and came back. I had intended to get to Francis peak (14.6 miles) but I was feeling nauseous from the start, and was getting dizzy. I was going to turn around after 8 miles but just kept going. Started feeling a lot better after 10 miles. But by the time I reached 12.5 miles I had been out for 3:45 and decided it just wasn't my day. Fortunately on the way back I ran into a couple of other runners. It was a big help having someone to run with and I'm sure I came back a lot faster because of them. Much of the trail was single track, and overgrown, had to watch for roots/rocks. The steepest part of the trail, from mile 4.7 to mile 8 or 9, is really rocky and technical. Coming down that section really beat my feet up. In the overgrowth, my shoelaces kept getting untied by hidden branches.  Around mile-ish 11 there is a steep climb up and over a cirque (?), kind of a four limbed scramble, harder to descend than to climb through this section. Although I didn't feel well, and moved extremely slow going up, I'm really happy to have gotten this run in. I'm hoping to eventually run all sections of this course, and today was a mental victory for me. I was out for about 7 hours. My left ITB started to twang a bit the last few miles, but held up great considering the elevation gain/drop (I'm still trying to figure that out). Though I was pretty tired toward the end, I didn't bonk!  Hope I burned some calories.
