I'm getting into a groove on the treadmill. Today I ran 4 miles in 51:19, without any foot pain! :) I finished up on the recumbent bike with 2.16 miles in 12 minutes.
I miss running/walking outside sometimes in the morning because it's so dark when I get up and head to the gym, but I'm glad the treadmill's feeling good. Listening to music and podcasts on the iPod helps/
