The SD 100 course covers five major areas: Mt Laguna Recreational Area, Pacific Crest Trail(PCT), Noble Canyon and Indian Creek Trails, Rancho Cuyamaca State Park, and Lake Cuyamaca. Course Maps, Elevation Profiles, Aid Station Locations, Detailed Turns, Crew Access, Mandatory Cut-off Times, and Pacer Allowed Legs can be found below. Pay close attention to applicable course markings and review the overall course map to have the big picture of the course. There have been instances, of course, marking vandalism in past races. As such, we recommend carrying a copy of the course maps and/or detailed route directions for sections that you are unfamiliar with.
