At the 2013 in some lake 24 hour ultra classic I suffered from severe [[Nausea|nausea]] and my race was terminated after 47 miles. However, this race gave me some interesting indications of what may be causing my nausea. Here's what happened…
* Before the race, I was feeling strong and my [[Three Phase Taper]] had gone well, hitting 190 miles in my peak week.
* I slept well the night before the race, and had a ketogenic eggnog for breakfast. (8oz Heavy Cream and an egg, around 1,000 calories.)
* The race started well, and I ran the first 15 miles without pausing.
* Around mile 16 I started drinking a little, but with hindsight not enough. The weather was cool, and I did not realize quite how much I was sweating.
* My mouth was dry, but I did not have the normal sensation of thirst. I can't explain this (yet).
* Around mile 20 I started fueling with a mixture of coconut oil, Macadamia nut oil, and Nuttela. This mixture seemed to go down remarkably well and I had no digestive problems in the next little while. This formula is liquid, but contains very little water as it is nearly all oil, which may have been misleading as I was drinking, but not hydrating.
# I got slightly behind on my dictation, which caused my body to release a hormone that reduces kidney urine output. This hormone (vasopressin) can cause nausea, which further reduced my fluid intake, which in turn reduced my blood pressure. My symptoms were then caused by a combination of vasopressin and low blood pressure.
I will continue to research nausea and Vasopressin, but my main conclusion is that I need to ensure I'm drinking enough fluids to maintain my urine output.
