Building the run

I am trying to work on my running (slow jogging really) so I can improve my triathlon times.  As you know the run segment of my triathlons are like a huge battleship anchor dragging the swim and bike segments under the water like they pissed off the mob.  So I am doing the couch 2 5k program to help me to get up to speed and keep me one track. Otherwise I would just slack off on the run workouts like I always have. I have been having some issues with my shin muscles getting really tight and making me slow way down.  I found some good stretches to do to help me with it but I wanted to see if I could get some inserts for my shoes.  At some point (years ago) someone told me that I overpronate and needed motion control.  I thought maybe I could use an insert that would increase the motion control.  Anyway, I got to Fleet Feet in Charlotte because they are serious runner people and will know what I need.  The guy did the whole shoe fit process where I had to walk and jog barefoot. Turns out I have a teeny bit of pronation and collapsing arches.  The shoes I bought on a wicked deal at the end of last season (and are big motion control shoes) are causing some of the issues.  CRAP! This also means......you guessed it.......new shoes needed.  Fantastic!  I tried out a few pairs of shoes that the guy brought me and ended up with Brooks Dyad 6 running shoes.  They are a neutral shoe which good because I could then add an insert that gave me a little more control and fixed the collapsing arch issue.  So far they are feeling pretty good.  I am hoping that the new shoe setup and the stretches eliminate the shin tightness so that I can continue to suffer as I work at the run.  I am hoping to be able to jog the whole 5k of my 1st sprint triathlon at the end of March.
