Accelerating the program by running every other day?

Has anyone tried just going through the program by running every other day? Week 1: Monday, Wednesday, Friday Week 2: Sunday, Tuesday, Thursday Week 3: Saturday, Monday, Wednesday

etc...etc?

I have been doing this and am now on Week 3 Day 2 and I am wondering if I may doing damage to myself. I'm pushing myself and running through a bit of pain but I think I can keep going at this pace and try to complete the program a little faster than 9 weeks. I want to be able to just incorporate longer runs as part of my workout routine soon so trying to push through c25k to get me ready.
