Race details and course
The 2026 courses will restore many sections used in earlier decades. A full Course Reveal and athlete guides are planned for January 2026. Courses are marked using ribbons on clothes pins, occasional flour, directional arrows, and wrong-way signs. Aid station maps, profiles, and driving directions will be published with the Course Reveal. Crew access is permitted at many aid stations unless explicitly restricted.
