Runners follow an out-and-back course for the race at the Lewis & Clark Half Marathon, which starts and finishes in Granite Lake Park in nearby Clarkston, across the state line in Washington. From there, runners follow the route almost entirely along the Snake River, following the bends of the river as it curves its way southward down to the half marathon’s turnaround point in Asotin, looking out across the river at Hell’s Gate State Park.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
