Pushed it too hard?

Yesterday was a tough workout! On Monday I started to get a little cold. Nothing major, just sore throat, sneezing, sore body, stuffed-up ears. Anyways, I decided to skip out on the workout that night, but Tuesday I felt up to the challenge. I started off running. I ran fast. I ran 1.9 miles in 14:26 minutes. I decided to stop because I wasn't feeling the greatest and when I stopped I got dizzy. So I lifted weights for 10 minutes or so, then I went to yoga. I can't remember the last time I went to yoga class. Probably like 5 weeks or so. It was brutal. It was like I had to start all over again. Everything was hard. Today I am feeling better than yesterday so I am going to try to swim. I want to keep up on my swimming and everything else so when major training starts up in January I won't be starting from scratch.
