A.M. Must have eaten something rotten last night. Was not feeling good this morning. Resting HR was 66 instead of the usual 48. Felt nauseous. Went for a run anyway, but kept it short. Ate an apple right before the run, that seemed to help a bit. Ran with Jeff. Hyrum did not make it. We ran the first quarter in 2:21, and I really did not feel like I could go any faster. We finally caught the 8:00 guy around 2.5. Then we hit some headwind, we turned around and it became tailwind. Around 5.5 into the run I thought of Jeremiah 4:19:
My bowels, my bowels! I am pained at my very heart; my heart maketh a noise in me; I cannot hold my peace...
There is a good one in Lamentations 1:20 as well, which I found while looking up the reference on the first one:
Behold, O Lord; for I am in distress: my bowels are troubled...
However, a mile later I started feeling better. We picked up the pace to sub-7:00. I ran to Jeff's house, dropped him off, then added the extra distance to make it 10.02. Thought of going a bit longer, but decided to err on the side of caution and finish the distance later tonight if I really felt better. Total time was 1:13:58.

P.M. Stomach still feeling troubled. I set a dubious PR on this run for the number of different types of foul emissions from both ends of the digestive tract. Started with 0.5 in 3:44 to find Benjamin. Then 2 more with him in 16:14. Evaluated how I felt, and figured I should be able to handle another 4. Started with a 7:36 mile, feeling painful in the stomach, but nothing I cannot run through. Next mile in 7:05. Started feeling weak, like I wanted to walk home, or better, just lay down and not move at all. But the home is now 2 miles a way, so I'd better run, 2 miles of walking would be a long and painful walk with a sick stomach. Stopped for a VPB hoping it would make me feel better. Started running, still feeling weak, focused on a goal - keep it sub-8:00. After about half a mile I did not feel any better, but the pace got faster - started running 7:15 pace. Then about 3.35 into the run all of a sudden I started feeling extremely weak, I do not remember feeling that bad at the end of my worst marathon, and soon I found out why. A few seconds later I threw up, first time in 7 years. When I thought I was done, I started running, but was still feeling very weak, and for a good reason. I had more stuff to throw up. I stopped, finished the job, and all of a sudden felt almost normal. Finished the rest of the run at around 6:50 pace, 29:36 for 4 miles.
I think this experience provides a good case for the brain-governed fatigue model. I did not have any less glycogen in my muscles in the moment of weakness right before throwing up when I probably would not have been able to sustain 8:30 pace than a couple minutes later when I was comfortably running 6:50s. So the most sensible explanation of what happened I can think of is that my brain sensed extreme stomach distress, and started shutting down the muscles in response to facilitate coping with it. When the distress was over, the muscles started receiving normal signal.
