Mile 20

I feel a bit like I've hit the figurative mile 20. Many people say that when you hit mile 20 in a marathon, you hit a wall.
It started about 3 weeks ago; I felt unusually fatigued physically, but even more so mentally. My desire to go out for runs diminished, I overslept on several mornings, completely missing my alarm.Then on my last long run, I had excruciating pain in my left knee; I had to walk/jog the last 2 miles of a 17 1/2 mile run. I think it was a combination of dehydration, worn out shoes, and not being completely mentally in it.

At this point, I should be excited, I should be preparing, I should be grinning ear to ear, right? I've never planned a wedding, but I feel a bit like what I think most brides do leading up to the big day: I wanna get it over with already!

But that just seems like such a crappy way to enter into a race. After all the hard work and training I've put into this, I want to enjoy it! So, I'm guessing I need to do now what I'll need to do at mile 20. Take a sip of water, a bite of PowerBar, a deep breath of air, say a prayer, suck it up, smile, and just keep running.
