Hey jschwab thanks for checking in with some more information. Since you're the expert here, do you mind if I ask your advice?

I carbed up a little this morning prior to my workout, but my pace was much slower today than it has been in the past - by just over a min/mile. The legs just weren't turning over like they did prior going LC. My theory is that lack of glycogen from being LC is what caused that.

So I guess my question is, when you switched to LC, did you lose speed at first, and then regain it? I felt okay today, and fueled like clockwork during the walk, but my pace was shot!

BTW, I'm doing the Myrtle Beach Mini marathon, 3rd weekend in October. I know you'll rock the half! I'm so biomechanically screwed up that I'm hoping if I lose all this weight I'll be able to try running too, but my knees and ankles tend to blow up if I try with any meat on my bones. As it is right now, walking these distances is giving me a terrible case of achilles tendonitis.
