Registered for a half marathon

The Brookings Marathon, Half Marathon, and Relay is about seven and a half weeks away. A short time ago I had all but decided to wait until later in the year to run a long race. I can't possibly be ready by the middle of May. My better judgment is telling me to just run a 5- or 6.2-mile leg in the relay like I have for the last ten or so years.

But I registered for the half anyway. I'm not sure what changed my mind. It's going to be a big challenge, which is something my running hasn't had for a number of years. I'm excited about it, and more than a little worried.
