It is very interesting reading how everyone's training is progressing, so I thought I would share my story.
A little background on me - I had 8 knee operations between my 15th and 33rd birthdays, so I have always assumed running was out of the question.
I was in pretty good shape, so I decided to celebrate turning 45 by walking a local half marathon. It completley hooked me and over the following years I was successful in all of the halfs I walked. I could chug along at under a 15 minute pace and was quite comfortable, always finishing strong and never getting swept.
As I approached my 50th birthday I began to see more about the run/walk method as well as Chi running. I decided give this a try figuring that maybe combining the Chi technique with the run/walk discipline would allow me to run in the races I love.
In the last year I have transitioned to a run/walk method. I had hoped to work up to more running than walking, but through trial and error, LOTS of reading and 3 halfs in the past 12 months trying different schemes I have landed on a weird marriage of 3 well known plans:
My basic training plan for a half is the 14 week plan from Marathoning for Mortals. For speedwork I add in Yasso 800s once every ten days from Bart Yasso's Perfect 10 for half marathons and last but not least, all of my running is done at 30 second walk/run intervals as advocated by Jeff Galloway.
I have tried longer intervals and had actually worked up to 3:1s but my knees protested so much that I was really debating on what to do next.
In the middle of this struggle and feeling like a failure as a runner I happened to read Amby Burfoot's article in Runner's World about running the Athens marathon with his wife and son. He wrote that he did the Athens using Galloway's intervals of 30 seconds!! It was an OMG moment for me - if a person with Amby's running credentials could do 30 second intervals, I shouldn't feel embarassed or ashamed if dialing down to that level worked for my body.
Long story short - I settled into 30 second intervals at the beginning of March and since then have set a new PR for the half (by 7 1/2 minutes

), have dropped my average mile times by over 1 minute from my best longer interval times and my knees are
I've got 6 miles as my long run this weekend and am very happy with how my DL training has gone thus far. I am getting much better at "feeling" my pace and have actually been doing negative splits on all of my runs.
I am also really enjoying my new "toy" - I upgraded from the Garmin 205 to the Garmin 610 about 10 days ago. It is TOTALLY worth the month of pb and j lunches I am now packing
Good luck to all as we train into the summer heat! Stay hydrated, keep cool and train smart!
