You can't slack off on the running/walking thing for two months (esp. when you are out of shape to begin with) and expect to just jump right back in there where you were (same ability) before you started slacking.
I'm registered for some 5Ks, and I'm still doing those. But my personal goal for running is to be able to run a full mile without stopping. This morning I ran/walked (mostly walked because my calves felt like they were on fire) 1.03 miles in roughly 22 minutes. My best pace was 12:57/mile when I was jogging. I want to get my mile down somewhere between 10-13 minutes. I know it's a big range, but I have no idea what I am actually capable of since I've never done it before.
I'm going to alternate days. One day, I'm just going to do a mile, but focusing on my pace and running more of it than the previous time. The next day, work on my 5K run/walk.
Oh, and get to the gym as often as I can. Those are my goals. Tonight I'm planning on Kick and Power.
