You can't work the muscles consistently every day. I too want to continue to grow thighs and calves. In addition, I need my glutes and butt to stay in shape for running. What I do is cycle back and forth with a preferred activity for majority of week, while still doing the other. This keeps overall muscle tone up, as well as the general "wind" level. I think you would find that your running is improved by contininuing to try and work in the leg exercises!
