Anyone riding in the Balance Bar Sprints race?

It's my first time entering into this thing and I was wondering if there were any veterans out there. I'm kinda nervous about the running part because I don't run very much. I've been training but it's still nerve racking. What's the race like?

For those of you who don't know much about it, I highly recommend it. It looks like lots of fun and a great challenge. Go here to learn more:
