Training continues: A Crappy Run

Today I was scheduled to run 15 miles. Instead I only ran 6, and I had to stop at 4.5 miles due to GI issues. I don't know what causes it or what to do about it, but well over half of my runs are interrupted by pitstops to use the bathroom. I can go an hour or two before my run or five minutes before my run; it just doesn't seem to matter. I've had this problem before, but it used to only affect me when I ran in the morning. Now it doesn't matter when I run. I'll try to find an answer to this problem. In the meantime I guess I'll just run close to public bathrooms.

Tomorrow, I'll make up the 15 I was supposed to run today. I may also run a few easy miles at lunch in an attempt to jump start my plumbing.
