I wrote kind of a long ramble about many things that I will eventually finish and publish. But for now, I'm focused on these words that my coach emailed to my team, almost 4 years ago, before the best race of my life:
You have to use what you know and feel about your fitness, the weather, and the course, and your experience, to sense the right effort in the early miles. Ultimately in a marathon you don't achieve a goal like in the rest of life, but prepare yourself and take what the day gives you.
Don't let your watch tell you what to do. It is only there for your entertainment.
You are ready.
I am ready. And I'm racing Boston. And that is the most wonderful thing there is.
