Just keep walking... just keep walking...

I've got a few more letters in my alphabet now.  Last week's training walk was very, very difficult - a lot of hills, and I started first thing in the morning without a drop of coffee or any breakfast.  I actually had to stop and sit down, near the top of a particularly steep hill, just shy of the 10-mile mark.  I have NEVER stopped on a training walk.  I'm hoping it's not a bad sign; just a sign that I shouldn't embark on 10+ routes without some sustenance.

Here is B, X, Y, backslash, and I.
