I walked three miles in one hour today on the treadmill at 1.0 elevation. I did not get out of breath, I even talked to the gal on the treadmill next to me helping her with some questions she had about starting up her treadmill...NEWBIES, haha, (got just a little out of breath but was able to talk decently). I am getting stronger and faster on that treadmill and wanted to note that in a blog. I have been pushing myself to go beyond limits I just haven't done in over 15 years. My next goal is to do a mile in 15 minutes, and work it up to where I will make it a whole hour. Maybe I'll be able to do a 5k soon...that would be so awesome!
