I jogged!!!!

I am so excited...I just just have to tell you...I JOGGED this morning! I went for my usual walk on the treadmill and realized that walking at 3.2 mph with an incline, my heartrate was up, but my breathing was normal, not even a bit strained. So, after 2 miles, I thought I'd kick it up a notch. I went up to 4.2 mph, and started jogging. About 2 seconds later I thought to myself "WHAT ARE YOU DOING??? YOU ARE GOING TO KILL YOURSELF!" But, I lived. I jogged 1/4 mile, then slowed down and finished my walk. Ok, I know it's not that far, but HOLY COW, I haven't jogged on purpose for years, if ever! That will now be my new goal, to jog at least 1/4 mile, and hopefully increase that distance! I'm just so excited! I guess all this walking is doing something, even if the weight isn't coming off like I'd like.
Thanks for listening/reading...I just HAD to share! :o)
