I signed up - now what?

So, my friends have created a team to walk in the Susan G. Komen 3-Day, 60-mile Walk for the Cure in Washington DC in October. I've been looking for a way to contribute more, to be more connected and more participative in the world around me. So here it is. I signed up.

and now I need to figure out what this means... and I guess I should go for a walk, huh?
