Coach Husband and I set out to run 7 miles tonight. The first two miles were good. Actually they were better than good (9:38 and 9:26 respectively). By Mile 3, I was starting to experience a nifty, stabbing feeling just inside my ribcage on my right side. WARNING: GRAPHIC DESCRIPTION AHEAD: Actually, it felt like someone was shoving a blunt metal object into my gut and twisting it. It hurt like a beast. Originally, I attributed it the big increase in my activity level over the last week and a half, figuring that my abdominal muscles were just a little twinge-y. As we progressed through Miles 3 and 4, the stabby twisty feeling got progressively worse and, as the my pace got slower and slower, it occurred to me that it was sort of like a side stitch, but not quite in the usual side location, since it would go away if I walked or stopped moving altogether. I tried to ignore it/run through it, but by Miles 5 and 6, I couldn't ignore it anymore. Those miles just plain sucked. I couldn't catch my breathe. I alternated between wanting to cry or scream because I was so frustrated. My head was in the game, but my body wasn't cooperating. This is new. Usually my mind wants to quit long before my body runs out of gas. On top of that, I felt like crap because Coach Husband was feeling just fine and I felt like a total failure and like I was holding him back. To his credit, he was incredibly kind about the whole thing. During my frequent walking/gasping/whining breaks, we tried to figure out what the hell was causing this. By the start of Mile 7, I still felt pretty crummy, but not as bad, so I was able to do what Coach Husband wanted: run the last mile in less than 10 minutes (9:58).
After dinner, I turned to Dr. Google. And, as it turns out, I'm not the first runner to experience this problem.
