I'm Going to Redo W3D3 of #C25K

I did complete it, but I don't think I'm ready to jump from 3 minute runs to 5 minute runs yet.  I can do the first 2 minutes ok, but that last minute I feel like I'm dying.  My breathing is out of control.  Instead of killing myself to stay week for week on this plan, it might be good for me to week 3 over.
