smileyk8 - you think the slow start is offputting? I was wondering if it was the same sort of phenomenon you see around here after people do the marathon (I feel ridiculous even typing this!) and then don't do anything for a couple of weeks.

I am thinking we are the wrong person to answer that question, given that this is a "graduates" thread. I know there have been people who have stopped due to injuries, but around here, I hadn't noticed a lot of fall-off at that half-way 20 minute run mark like the writer of that article mentions. Of course maybe I wasn't keeping good track. I know that for me, C25K was great up through that first long run, and then around week 7 or 8, I started kind of doing my own thing.
So, advice. Obviously, I'm not an expert or even a very experienced runner, so take it with a grain of salt. I am following this training plan in Running for Women and it includes some speed workouts. Hills are a natural part of my running environment, so I don't tend to use the incline a lot when I'm on the TM - I vary between 0 and 3, but don't usually run at an elevation of more than about 2. Speed is so personal, as you know, and in some cases, treadmill specific, so I can't really advise on numbers. But my interval workouts include runs at a faster pace - such that I'm breathing and working pretty miserably hard - for different amounts of distance. I have been doing 400's and an 800 this past week. 400 is about 1/4 mile, 800, 1/2 mile. Recover for half the distance and then do another.

Last week was 2x400, 1x800, 2x400. On my treadmill, I set the pace to 6.2 for the 400's and 6 for the 800's, but it sounds like you're running that fast on your treadmill as it is, so you'd need something faster to turn up the heat.
My best advice would probably be to read around about this stuff (runners world, etc.), and possibly, if your training plan doesn't include it, don't worry about it for now. I think that beginner's plan is pretty much designed to get you to a point where you can do the distance. Speed work is designed to make you faster, obviously, and is probably not the main concern in a beginning program.
Hill work will make you stronger, but when you first start out, I think it is a lot like suffering. However, it proves you can get used to anything - I used to whine about the hills to even get out of my neighborhood - I am not sure I whine about hills at all anymore.

That may change again come summer, though.
