Sucky Workout-TMI

I was really looking forward to my run today it was Advanced Speed with lots of hill work, I did do it but dont really feel like I got a GREAT workout from it like I should have. Why? Because an hour before I went to the gym I developed a stomach "issue" so at the gym I had to get off the treadmill 2 times to run to the bathroom! Not sure what hit me because now I am fine! Ate right on points today, nothing different to cause the stomach problems so there is no explanation for it! Oh well, just have to work that much more harder tomorrow.....
