Well it's raining here in Indiana still, so I tried out the rollers again. I really do like roller. I'm nowhere near being able to do 12 miles, 4 miles today kicked my a$$. My husband thinks they are dangerous, and doesn't want anything to do with them, he won't even watch me on them. Unfortunatly these roller are not mine and I'm going to have to give them back, but I am so going to get me some for the winter months!!
