I'm at least a year away from any Marathon consideration, but when/if I get there, I'll be researching which one(s) to try. Opinions? I'd like to BQ on my first attempt, so I guess I don't want anything too hilly. I ran the SF Marthon a few times back in the 70's/80's, and the hills didn't really bother me then. But now I struggled through a 10K in GGPark. Thanks,
