I started week 2 of the C25K last night and I was unable to run every 90 second run. I did the first one with no problem but then the front of my legs really started hurting. I *think* the pain is too low to be shin splints though. Its really frustrating. I can deal with the burning muscles and work through those but this pain is frustrating. When will my muscles adjust to this darned thing called running? I'm looking forward to the day when I'm relatively pain free! Oh, the pain is low on my leg, almost where the the foot and leg meet but slightly higher. I'm not sure how to stretch that muscle or even in which direction to stretch it. Very Frustrating!
