First Half Marathon

RandomMiranda

I've been wanting to train for a half marathon for a long time, and I think I'm finally ready to committ. Has anyone done the Dallas Rock 'n Roll half or the Austin Livestrong Half? Any recommendations for a first timer? I've done lots of 5ks, including big crowded ones, so I'm more interested in the type of course and the overall atmosphere and organization. Or a better expo or gear? I've been to the Austin to support a friend, but didn't see much of the course. I live over an hour from either location, so a short trip and an overnight is a given.
Any other general tips for a first half marathon would also be appreciated, or new friends who are also training.
