Stacy: Oh, the job thing. That explains why you're not coming. Yeah, jobs interfere with our real lives, don't they?

I hope your run works out. I do have to say that I find my muscles appreciate the run as it alleviates the not-so-pleasant after-effects of the biking.
Allyson: I'm glad you like my inspirational quotes--they're nothing I would say to anyone else, but they do motivate me. It's hard to take yourself seriously when you're calling yourself names. And it's probably funnier because I've never been to boot camp. In bigger news, though, WTG with your W4D1 success!!

That's so great that you and your DH can run both together & separately. Together, for the sense of support & accomplishment; separately, so that you can challenge yourself as an individual & figure out what works for you. Be sure to take care of those ankles, and get a rest day in there. P.S. Are you wearing running shoes--not XT, or sneakers, or walking shoes?
Kim: Add me to the list of people that got--and still get--nervous with new weeks & goals. I love the challenge, though, and I think the nervousness means we're taking our goals seriously. (But not so seriously that we won't go outside our comfort zones.)
Raenstoirm: 
with W5 being easy & do-able. You know, I think you're onto something with the focus on distance--especially if it helps you with the mental game. I did C25K for time and I have to agree that it seems easier to squeeze in that last bit of distance than to go another couple of minutes.

Anyway, congratulations & you're going to do great with the rest of the week.
ABOUT ME: ALLYSON'S QUESTION ON RW & RUNNING
Yes, a Run-Walk (RW) is exactly what you describe, and your question about intervals is a good one because I'm not sure quite how to answer.
So here's a preliminary answer, long as usual.

I try to be consistent in my intervals right now, as I'm new enough to running that I'm never quite sure if my desire to walk is physical or mental. KWIM? Sometimes that consistency doesn't happen, of course. But when I deviate from my plan it's to run longer intervals, for example if the run feels easy. I really try not to run shorter intervals than my training program recommends.
My interval strategy, and my 1/2 strategy, comes from John Bingham's
Marathoning for Mortals 1/2 marathon RW plan.* His recommendations are "bare minimum" RW intervals I try to achieve. Right now, they're a 3/1, I think. (Bingham's intervals change over the course of the program: 3/2, 4/1, with a suggested goal of doing the 1/2 with a 4/1.) Since I've been doing Bingham's program concurrently with C25K my training is somewhat strange--I transition from a straight run to RW instead of sticking to a RW interval on my LRs. Because I'm trying to listen to my body, my interval periods also change with the run. Some days it's a 3/1, some days it's a 5/1, some days it's a 6/2, etc. On race day, though, I'm going to try to do a RW interval throughout, hopefully a 10/1 or so.
*NOTE: Bingham's intervals are just guidelines, and he encourages people to choose the intervals that feel right for them. I'd eventually like to be able to do longer intervals for my races (if I do intervals at all): maybe run a mile, walk a minute or walk at the water station, run a mile, etc. Jeff Galloway is also a proponent of the RW, and his plans are also worth looking at.
Lots of WISHers and marathoners in general use a RW strategy. I met several people on the Disney course using their own version, establishing their own rhythms & intervals depending on their training & the race day's needs. Many RWers have a better overall pace than I do (not that that's difficult). I hope no one here would feel they aren't a runner if they decide that the RW is what works best for them. (It's too early for any of us to tell, I know.) As for me, I'm interested in experimenting right now. Who knows? I might decide I'm a dedicated RWer in the future.
