I can't definitely say for sure yet because I haven't tried to increase my mileage much yet. I will say though that the calves do feel better. That daily stiffness and aches seems to be on teh decline.
One thing I had to come to grips with was taking one step back before taking two steps forward. The first morning after doing some of the really hard/deep massages my calves were really sore. But, but the second morning, they felt substantially better than they have in a long time.

www.julstro.com -- it's where I got the information and advice from. Julie, the lady that runs the web site really seems to know her stuff and her books are easy to understand.
I haven't started the ART yet, but perhaps will next week. I need to see a specialist for that.
