I just did the Race for the Cure here in Portland on 9/23. It was my third year. There were 46,000+ participants. It's awe-inspiring, and as I'm walking with my teenage daughters, I always think that events like this might be what makes the difference in their lifetime. Pink is for survivors. You should get a shirt with your registration. As for fundraising, that's optional. When you register, there will be a letter that you can email to your friends/families inviting them to sponsor you, though. (That's how it is here anyway.) You'd be surprised how many people who aren't able/interested in walking are happy to support you. Go for it!!!
