Course
The marathon is two full laps of the 13.1-mile loop, which runs through meadows and over a big granite dome. The exposed granite section is hot, so runners should carry water between aid stations.
The course is marked with signs at each split, and a spot near mile 8 of the loop allows self-placed drop bags.
