I am having lower leg troubles when I run (calves, Achilles tendon, and plantar). I stretch regularly -- based on stretches recommended by a PT -- and do strengthening exercises (e.g., eccentric heal raises). I suspect that my long Sunday bike ride is contributing to my lower leg issues and am considering moving my cleats all the way back (in addition to a pro bike fit). Has anyone had any experience with this? Positive/Negative effects?
