This morning, I wanted to get a mid-week long-ish run in, so I got up at 5 am in order to try and beat the heat and get 8 miles in. I got up, had half a piece of toast with peanut butter and some honey and a cup of coffee -- I mention this b/c I think it plays a role later on -- then I got dressed and headed out the door around 5:45.
Even though it was dark and certainly cooler b/c of the dark and the early hour, it was still 81% humidity out there and the air felt thick and hazy. As I started out, my breakfast felt a little heavy in my tummy, but I figured it would settle out within a mile; besides, this is a regular pre-run breakfast for me, so the tummy is used to either this exact combo or something similiar to it. But as the run continued, I started to feel worse and worse. I don't know if it's cuz I was so hot (sweat was just sitting on me), or if I didn't digest fully, but at mile 2, I literally thought I was gonna blow chow.
I stopped there for moment, and leaned down -- face towards the grass in case I barfed -- and took a few deep breaths. I haven't felt nauseous on a run in over a year (back then, stomach issues were the order of the day, but my tummy toughened up and I haven't felt sick during or after a run in quite some time), so this was odd. While I rested for a moment and let my nausea pass, I decided to turn around and do 4 miles instead of the intended 8.
Halfway back, I again had to walk b/c my stomach felt queasy, but then I resumed running and was able to round out the 4. Sucks, but I'm not gonna beat myself up over it. I'll adjust accordingly and perhaps tomorrow I will eat and drink differently before the run, and, maybe, just maybe, it will be slightly cooler too.
