I think that's part of my problem. Not knowing exactly which muscles that I'm individually warming up/stretching.
Picked up some KT Tape yesterday. "Kinesiology Therapeutic Tape" - watched the youtube on the use - supposedly it aids in preventing the injury.
KT Tape provides excellent support for these muscles during unavoidable activity, reducing aching and tightness in the calf. This application also provides inhibition of the muscles to promote relaxation and healing.
