I finished the C25K program a few weeks ago using just my indoor treadmill. And thought I was doing great running 30 minutes at a time!!! Tonight though, for the first time ever I ran outside. OMG what a difference. It's so much harder on real pavement. To make matters worse I am agoraphobic, so the anxiety of that combined with the physical demands made it really hard. I managed to get about 20 minutes done at a pace so slow that my long-legged daughter was able to just walk alongside me! She finally got bored and ran off like a gazelle! LOL. Oh to be young again! All in all it went about as well as I expected. My hat is off to all of you who are running successfully on pavement. I have a LOT of work to do.
