Error in Judgement?

The early week 'workout' was supposed to be Tuesday with the option of moving it during the week to allow maximum recovery from the weekend. I was a little busy with the house sickness on Monday so I adjusted and ran easy on Tuesday and did the workout this morning. I woke up early because I knew it would be 90-100 minutes for the entire workout. It took me near an hour to get out the door secondary to GI issues. I hit the crapper two times before 5 am. When I left I didn't feel great but not all that bad either. After a warm up I started the workout and was ready to bail out at any moment and make my way home. I actually felt really good for most of the workout and had a little GI issue on the warm down but for the most part running was the best part of my day. I was left with about an hour to get ready for work and my stomach was churning like gale force winds were in effect. I tried to drink, eat, and take in extra salt and no help was provided. Once I got to work, a glass of 7-up and a little more breakfast helped a bit more. After work I felt queasy and warm. Shit! Maybe I am sick! Tomorrow is questionable and I'll have to sleep on it and see where I sit in the am.

The workout looked like this: 4-5 X 8 minutes med-hard, with 3 min's. recovery.

followed by 3X 40 seconds hard.
