Best Kept Secret

from the Runner's World 2004 Marathon Calendar

"No one's heard about this one. It's only 3 years old, and runs along an old railroad bed through the Black Hills of South Dakota. You get bussed out to the start in Rochford, population about 25, a tiny old Western town. The course goes through meadows, forest, an old tunnel cut through the mountains, and across 30 bridges."
