I was thinking about you on saturday. I saw this woman while I was out running. Her running form sounded exactly like what you describe with your feet and your knees. I couldn't help but think she was going to have some pain in her future. Of coure, even with her form, she was way faster than me.
Your plan sounds like a good one. I can't wait to read your race report.
