Big Sur Marathon. It is a beautiful course. Cloudy the day we ran it, however. Will have to do it again. It has 19 hills.
The Big Five Marathon- It's a marathon you literally run through South African Savannah with Elephants, Rhinos, Buffalos, Lions and Leopards...OH MY! It says "No fences, no rivers, nothing at all separates the runners from the African wildlife."
