It's through the RRCA, I think. There's not much info. on their website-I had to check the club websites to find out when the races are.

Dreaded Druid Hills is June 30th, the day I get back from the cruise. So I won't be able to run that one. :-( I've run Baltimore twice though-half marathon in 2004, full marathon in 2005. I heard that they're able to include Lake Montebello this year-should help with the hills in the second half.
