Summer 2012 Running Plan

My sprained ankle finally quit hurting at Easter, just like the Physical Therapist said it would. My torn meniscus continues to bother me after Long runs on Sunday. So I have stopped the Sunday Long runs and now run Hard/Easy six times a week. Actually, the difference between Hard and Easy is only .5 mi and I currently am at 3 and 2.5 mi for a weekly total of 16.5 mi. I want to increase my weekly mileage but adding a half mile to the hard run seems to aggravate my knee with the torn meniscus. My plan is to increase my daily run by 1% or 50 meters. My hope is this will allow me to increase my mileage without big increases in my longest run.
