Prepping for the Japan Day Race

I know it's only Wednesday, but I think it's never too early to start planning a race. In this case, the Japan Day 4 miler. I actually started thinking about it Monday. I've already run Monday and did a speed workout last night. That means no running Wednesday and Friday; 30 minutes of stretching instead. Tabata intervals on Thursday, easy 10k Saturday, then run like a bat outta hell Sunday. My goal is to run between 6:30 - 6:35 and further drop my 4mi PR this year.
