My new “training” plan

So, I’ve decided that I’m not going to do the KC Marathon.  I really wanted to qualify for the Boston Marathon, but I just don’t have the time to dedicate to the training I’d need to hit the 3:10 mark for BQ.  I still might do the 1/2 marathon, but I dunno.  There is a whole different blog post why I really don’t like doing races that dips deep into the dark corners of my psyche (and 7th grade track repressed memories).
So, for now, I’m going to focus on being a fast short to medium distance runner.  Anything under 5 miles, I know how to pace myself to finish at a good time and have plenty of gas left to knock out a low 6 minute mile.  Anything more than 5, and I’m unsure where to hold up, when to speed up, etc.
Even though I’m not training for anything, I still need some form of structure otherwise I’ll just keep doing my favorite distance of 4 miles over and over.
My plan is to push myself out of my comfort zone and see what I can come up with.  I want to alternate my short and medium runs and have them add up to 10 miles.  So if I do 3 miles today, my next run will be 7 miles.  If I do a 9 miler, I can “reward” myself with a 1 mile run, etc.
I’m also setting a pace goals for myself, so I have a PR to shoot for every run:

Distance	Goal Pace	Current PR
1 Mile	5:40	5:46
2 Miles	5:55	6:35
3 to 4 Miles	6:05	6:12
4 to 5 Miles	6:25	6:35
5 to 6 Miles	6:30	6:43 6:39
6 to 7 Miles	6:30	6:43
7 to 8 Miles	6:45	None 6:56
8 to 9 Miles	6:45	7:07
9 to 10 Miles	6:45	7:31 6:54
10 Miles	6:59	7:14

I’d like to get four runs in a week, which would give me about 20 miles a week.  If I can stick to this plan for the rest of the year, and sprinkle in a couple of long runs, I’ll be able to get over 850 miles for 2009.  I’d be happy with that considering we had a baby last December, bought a house in June and other news that I can’t quite talk about yet.
I’d love to hear from other runners how they run when they are not training for anything.
