Let's take inventory after my long walk yesterday:
Head: Still pleased with itself and thinking four hours on the treadmill was a pretty good idea.
Back: Pretty sore. Walking did that??
Shins: I have MUSCLES in my SHINS? Owwie owwie ow ow ow!
Feet: Tender, aching, blistered, tiny bones actually snapping in two. TOTAL DISASTER.
So all in all, not too bad. Biking felt fine, but because of my ridiculously sore feet, and out of an abundance of caution, I decided that water would be a better place for a run than land today.
