I've always been an outdoor exerciser but as I get older and less excited about running in 6inches of snow on a 10 degree day I've decided to start going to my neighborhood's rec center. They have an indoor track along with plenty of treadmills.
I've never, ever run or walked on a treadmill. Is it hard to get used to? Borning as hell? How can I keep up my motivation while running in one place? :D
