Of course there's a catch. When is there not a catch? But we promise this is going to be simple. Have you heard about the Nike+ Human Race? 25 cities worldwide, one million runners all running 10k on August 31 to come together as one great voice, empowering the World Wildlife Foundation, Lance Armstrong's LiveStrong, and ninemillion.org . Oh yeah, you say, I've heard about that. Well how would you like to make it official that you're one of those million people running for the Human Race?

Now, everyone that registers for the Nike+ Human Race will receive a white Nike DriFit Hat emblazoned with the outlines of runners worldwide. All that you need to do is register for the Nike+ Human Race at home or at one of our Nike Club RunChi training runs. If you register at home, simply print out your confirmation page and bring it to one of our training runs. That's all, we swear!

Don't forget, there's a $35 registration fee, but we think you're getting more bang for your buck: in addition to contributing funds toward one of the 3 Nike+ Human Race charities, your registration also acts as your ticket to the awesome after-party and finisher concert with Fall Out Boy. All for thirty-five bucks. Register for the greatest race the world has ever seen and get your free Nike DriFit Hat.*

We'll see you out there, and we know you won't regret joining the Nike+ Human Race!

*While supplies last.
