Course Map: The Lost Trail Half Marathon

Runners follow an out-and-back loop course along paved park roads and dirt trails that wind through Folsom Lake State Recreation Area at the Lost Trail Half Marathon Challenge, which starts and finishes at the beach overlooking Granite Bay. From there, the course first heads south along the shoreline of Folsom Lake, along some small hills at first, followed by steeper hills later on in the race.
