I had MAJOR stomach issues on my run tonight. Got about 35 minutes in, had to bail off the treadmill for a quick bio break. Then back on the treadmill running, but stomach started acting up again, so I dropped from a run down to a walk, 4.0 mph but bumped the incline up to 6-7% and did another 30 minutes. Then stomach really let me know it wasn't happy, so I called it a day (after another bio break).
I'm guessing it's due to the very cheesy omelette I made for dinner last night. dang.
Well, if nothing else, this might cure me of my cheese addiction.
and by the way, this post is probably TMI (too much information), so feel free to ignore or pretend you never read it.
