Lessons I've learned but always manage to forget

Just a few running lessons I've learned over the past few years that I always manage to forget. These have all come into play at some point in the past week's training. I'm writing them down in hopes of remembering them in this final week (!!!) before Fairfield.

1. When you have to go while you're running you can combat it, but it takes lots of effort and concentration. And you only end up buying time until you find a bathroom--it never truly goes away.
2. Big breath in, big breath out. Repeat. That is my running mantra. Maybe I inherited crappy sinuses from my mom, but my breathing is not spectacular. No asthma, just inefficient breathing. So I always have to remind myself to do big breaths, drawing them in/out over two steps.
3. Always, always start off easy and you will be able to finish hard. I've done a good job of tempering the first mile of my long runs while training for Fairfield, but I could stand to improve my pacing.
4. No matter how good you are at this running thing, you always have to dig deep. Always.
5. You don't need to be hungry to have a GU while running.
