For those on the treadmill for over an hour, I commend you! I get bored and hot.

Thanks for the treadmill responses. I do use a small incline and I try to vary it. Running on the treadmill IS more difficult for me because I'm always in fear that I'll step partially off the tread but then again I'm not graceful.

I did about 3.5 miles this morning. I need something to cover my ears! It was 45 deg out and while I was fine after I warmed up, my ears still hurt. I finished in 38 minutes but I had to walk a bit after the hills. I got so I can run up the hills (yay!) but I now have to walk for about 30 seconds after each one just to get my HR back down. The day will come when I don't have to do that, I am sure.
