Well, I got up late and Oldpossum had already returned from her graduation run. So after an initial "can I do this?" internal dialog I got on the hamster wheel in the garage.
I have to say 90 seconds of running really hurt. Didn't think I was going to make it by the 3rd run section but managed to keep pushing.
All I keep thinking about is all of you on here who are so inspiring and keeping me going. Thanks to you all.
