Galloway test run

Long run: 13km

Even before I signed up for the Stockholm marathon, I was considering adopting the Galloway approach for my long runs because I liked the idea of being able to run long distances without suffering from injuries and/or excessive fatigue. My very first attempt at running with walk breaks though was a complete failure because I didn't follow his recommendations at all, I just ran for 2km and walked for one minute. It was a disaster, possibly the worst workout I've ever done.
The second attempt went much better, I used a 4:1 ratio (4 minutes run, 1 minute walk) for all of the 8 miles of that workout, but in the end I didn't feel any better than after my previous longest run, 10km without breaks. Again, my decision on whether to adopt the Galloway approach or not was postponed.
That's when I signed up for Stockholm.
I spent quite some time sketching a training program, but then I started having doubts about it and I sent an email to Jeff Galloway himself, even though I was not really expecting a reply. About a week later I did get an answer from somebody in the Galloway organization: Chris Twiggs, National Program Director. Chris had clearly spent some time writing down a kind and thoughtful reply, and this alone made me want to go for the run/walk/run method, but not before another test... and that's how we finally get to today's run.
With my best time on a single mile I used Galloway's prediction formulas (see Magic Mile) to calculate my marathon pace and my run/walk ratio. Since I wanted this to be a test run, I picked the ratio that was in between the one recommended for my training (1:1) and the one recommended for my race (2,5:1), so that was 2:1. As for the pace, I still don't have very clear what they recommend, so I decided to pace myself based on the heart rate rather than on the timer.
How did it go? Well... I should check this tomorrow, but now it's 12 hours after I finished my run and I don't have any special complaints other than perfectly normal muscular fatigue. Maybe my left knee is a little bit funky but we'll see tomorrow. So I think I can safely say that the post-run is better, but was the run itself also better? Honestly... no. I didn't feel the elation of last week, and even though I'm trying hard to find some more words to describe what I didn't feel, I think that says it all.

So what do I want from my whole marathon experience? Do I want to feel good while running it or afterwards? I'll have to think about it some more, and in the meantime I'd love the input of anybody who read this.
