12,000 steps/Big Mac

I managed to run 5 miles this evening then walked for another 20 minutes to to get to 10km. Went at a pretty steady pace with a few "bursts" for the 5 miles. I think that I may have been able to keep that same pace for quite a while. It seems that I feel like stopping at about 20 minutes then if I keep going, the feeling passes. I wonder if aerobic exercise raises or lowers blood glucose levels? Maybe I need to do some Internet research on that.

I don't know why I am worrying so much about being able to finish the 5km run that I've entered next month. Yesterday, I walked from lower campus to West Ridge along the route for the run just to see how winded I would get going up the hill. Before I knew it, I was at the top not winded at all but almost falling on the ice a couple of times near the top of the hill. I'm excited about this change in my life. I never want to go back to being a couch potato. Losing weight has been incredibly difficult for me and there is some water commercial on TV that is a great reminder to me on how how many steps are required for each 100 calories (for me this number is about 2230 steps/100 cal). That translates to something like 12,000 steps per Big Mac i.e. it's not worth it to me. Fortunately, a Macdonalds anything doesn't appeal to me at all.
