same thing happened to me this afternoon. I ate a BIG lunch. Went for a run about 4 hours later. Normally this would be fine, but I ate a ton. I had pasta. The entire box is 8 servings and I had about 3/4 of the box

. I toped it with about 4-5 servings of Prego Sauce. I ran out about 10 minutes and felt like I was going to puke. I really am surprised that I didn't. I walked back. The entire fiasco took about 1/2 hour.
Man it was wierd. I am in fairly good shape, but just lost everything today. I have never had problems with eating too much before running and I ran Xcountry in HS. (I am only a year out of HS [19 yrs old]).
Ryan, man was the walk home embarrasing, I felt like crap since I couldn't finish what was suppossed to be a shorter run.
