If you can wait 'til December, why not try the California International Marathon (CIM)? It starts in Folsom, CA (about a mile from our house) and ends at the State Capitol in Sacramento. It is a net downhill and touted as one of the "fastest courses" in America. The weather was atrocious this year, but usually quite nice, with temps in the low 40's. Lots of community support; it's a fun one!
