Lobby: Getting Charitable Contributions

Hi All:

I've been enjoying reading the entries in this forum. Nice group.

I'm running my first half-marathon in a few weeks, and it occurred to me that I could use it as a way of getting charitable contributions for a 501(c)(3) organization I'm involved with.

Can anyone point me in a direction to learn about how to do this type of thing well? As far as the actual money, I can point them to the org's website and have them put "Jay's run" in the comments or some such. So at least I don't have to worry about collecting money.

Any help is welcomed and appreciated.

Cheers,

Jay
