I just read the book a few days ago. I also finished C25K a few days ago.
I wrote about this over on the C25K forums when I graduated, I'll just copy it here because what i wrote deals with the book, running barefoot and minimalist shoes 
-
I began working out in January, was getting in pretty good health, but
running is something I could never do, not even when I was young. I
love to bike, and I enjoy my gym workouts, but I wanted to both do
something I could do anywhere without any equipment and something that
I'd never been able to do: run.
When I began C25K on July 6th, I
could not run a block. But i knew that many other people had done this
program and that they had succeeded, and so I set out to do it exactly.
I printed it out and put it on my fridge.
Now I am fortunate to
have in my family a triathlete. My stepdad is 69 years old and still
swim-bike-runs them, and he wins his age group almost all the time. He
is an avid health freak and was really excited that I decided to do
this. He found, a couple of years ago, a philosophy of running called
POSE - similar in some ways to Chi Running, Evolution Running - a
barefoot philosophy with some other bio-mechanical theories and
exercises.
So I figured *since I had never been a runner and had
no bad habits to unlearn, that i might as well start off with POSE. I'd
read the book, I watched a video, I did weeks 1 on a football field,
barefoot*. Liked it. I asked my stepdad to join me once during week 2
to help me work on my stride, tempo, form and so on, which he did. It
was very helpful.
The following week I moved onto the rubberized
track that ran around the field. At this point I wanted shoes so *I
borrowed my daughter's Puma H streets which are pretty much a thin
strip of leather on the bottom*, as close to barefoot as I could get
without going to the Vibram 5 Fingers.
I followed the program
exactly, never running less, never running more, always doing the 5
minute warmup walk and adding a 5 minute cooldown walk as well.
As
an aside here, once distances were offered in the plan (week 3), I used
those instead of time. I figured my point was to get to 5K, not 30
minutes, and since I don't own a watch and I had this track available,
it was much easier to measure distance than time anyway. (I didn't find
out about the podcasts until week 6). So I ran it as 1/4 run, 1/8 walk
etc.
I went on a family vacation to central Oregon during week 4
and my dad helped me find a local trail with KM markers. I ran two runs
there, joined my my daughter and brother. Despite the crazy heat, those
were good runs. I also got to do a lot of hiking and realize how much
more fit i was becoming...a mile and a half, up and down mountains was
not only doable, it was enjoyable.
When I arrived at week 5 I
did the track the first two days. Looking at the third day's straight
no-walk run, I decided it was time to hit the street...or bike path,
anyway. I was a little nervous about my minimalist shoe style and how it would
adapt to asphalt, concrete, pavement. My stepdad assured me that my
running barefoot and nearly so had been strengthening my feet and that
I could run on hard surfaces without padded shoes...but never having done it, I was
nervous. I had decided on a real 5K to run and it was on the street,
so I knew I had to get out there at some point.
So I pulled up
Google Earth and mapped myself a 2 mile run. I did my warmup walk to my
start point, set my water down in someone's yard, and set out. I won't
lie, it was hard...mainly because in my head I knew I'd have no walk
breaks. But i did it, and it was one of the most satisfying runs
ever...because to me it was a "real" run.
Also, my feet did fine. *To
this point I've been injury-free...except for after the Oregon runs
when I was forced to wear shoes with a significant cushy sole (as my
daughter was running with me and she wore her own that I'd been
borrowing). I got some hip pain from those runs that did eventually go
away...but whenever I've run in the "running" shoes, it returns.* I've
since learned more about why that is, and will be getting my own shoes,
I just need to make a decision about one of two kinds. Anyway...
Weeks
6, 7 and 8 had some good runs and some tough runs. Sometimes it was
really hot (it was August) and sometimes I caught a cool evening. I
learned to map runs with lots of shade if I had to run in the daytime.
Sometimes I mapped myself a run that turned out to be much hillier than
i thought....but I did them. I let myself walk for a few seconds on
those....and that got me through. After those I returned to a couple
of favorite routes, flat 
I did the first run of week 9 and it
was hard. Really hard, not fun. Here i am so close to the end that I
can feel it, and it's gotten harder. And now I've gone and signed up
for a 5K...I HAVE to do this. Enter labor day weekend and a camping
event, music, friends, drinks...I took 5 days off.
This week,
Wednesday, I did W9D2 and it was FUN! I added the .1 miles to my 3
mile run so I could actually do a 5K and I DID it! Man, that was a
high.I did it in 38:55 - almost a 13 minute mile pace but I didn't
care...I ran it all and I knew I could do the real race in a week and a
half.
In the meantime *I'd requested a book from my library
called "Born to Run" by Christopher McDugal, and it came in yesterday.
I picked it up and started reading it at 8PM last night. I read it all
the way through, couldn't put it down, finished it around 2AM.I knew I
had to finish today - not this evening (when i prefer to run - never
been a morning person) But this morning. The love of running that
comes through in that book made me excited.*
*So I got up and put
on my duds and realized my daughter was wearing "our" shoes. Wow. I
really didn't want to run in the puffy running shoes. But that seemed
like an excuse to me this morning, it was too important to me to go
on and finish the program...so I put them on and set out on the same route I did Wednesday.*
*It
was harder,* *I could feel the muscles of my foot trying to feel the
ground through the soles and not getting the feedback they wanted*, but
I did not let that stop me. I just ran. When I got to a sunny part of
the path, I ran faster, back in the shade i slowed down. I ran as fast
as I could the last hundred yards, to where my water was stashed, and
then I ran past it, just a bit, to add the .12 miles I needed to call
my 3 mile run a 5K.
And i finished.
I have my 5K race on
9/19 - next Saturday. I will use my daughter's shoes for that, then I
will either get a pair of those for myself or go "all the way" and get
the Vibram Five Fingers. Not sure yet. But i know I don't want to run
in the thick soled running shoes anymore.
Do I LOVE running? I
don't know. There are times I feel good when I'm doing it and times I
do not. I always feel a huge sense of accomplishment when i finish a
run, for sure. I love what it has been doing to my body...muscles have
popped out in places I didn't know they were there. I can hike, I can
run, I can do a lot of things that were hard for me, or even
impossible, before this experience. I love that I set a goal and
worked towards it and accomplished it.
I love that I have
options open to me now....do I want to become a One Hour Runner? Do I
want to go for a half marathon? Do I want to work on my swimming
technique so I can do a triathlon? Do I want to keep biking and working
out and simply run 3 miles a couple of times a week?
I don't know yet. But it feels great to be able to consider the possibilities, and know I can do any of them if I choose.
So thanks, C25K, you have been an empowering experience.
