I realize I didn't post after running the Clearwater FL Marathon MLK Day Weekend.  I thought it would be a PR, but it turned out the humidity had other plans.

Around mile 17 my legs just fell apart.  As one guy described me as he hobbled along side me, "looks like you got a bad wheel." I could run for about 2 minutes then had to walk for about 5 minutes for several miles like this until another runner who had been trailing along at a similar pace and pain level found some friends at a water stop who happened to be a PT and Marathon competitor.  She saw our condition and gave us salt tabs and electrolyte pills.

About 2 miles later, my legs came back.  And strong!  I have my fastest last two miles of a marathon ever.  Turns out the humidity really zapped me of my electrolytes.

So now I really load up on the electrolytes when I run.  Hopefully this will get me past 18 miles without a bad wheel next time.
