Sometimes our bodies just need a break

Yesterday was such a beautiful day. The sun was out and I couldn't wait to get outside in the afternoon and go for a run/walk. I put my little guy on the bus at noon and went to the bank, when I got back I changed my clothes, grabbed my ipod and off I went. I started running and got about halfway down the street and felt totally exhausted:( I knew I couldn't quit so I walked the 3 miles. I was disappointed:( I was really hoping to run more...I just couldn't do it. I have been very tired the last few days. I am hoping that I am not going to get sick.
I have noticed the last few times I have just went for a walk(usually 3-4 miles) I feel more rewarded by my workout than I do when I run?! Does anyone feel the same? My friend who has lost weight recently says 'not everyone is a runner" just because you can run doesn't mean you "have to ". A lot of info out there actually says walking is better! What do you think?

Funny moment

Yesterday I was on the phone with my Mom and I am telling her about my progress this week and the conversation changes to me telling my Mom about the new jeans that I got the other day. My oldest daughter who is almost 16 is listening in on the couch next to me says "Mom, you bought/buy jeans in the junior section now?!" I said, Yes, Yes I do:-) I wish you could have seen the look on her face;) Priceless!

A question for all my fellow "athletes". Do you find when you workout to the extreme your weight on the scale sometimes shows a gain? I have really been pushing myself outside my limits and this morning the scale was up a bit. My eating hasn't changed, so I was just wondering if it was from working out? Can that be?
