The course is marked with orange surveyor's ribbon, gypsum chalk, reflective strips, chem lites, and signs. The primary markers are orange surveyor's ribbons.
Multiple orange ribbons are hung prior to major turns. Runners should see confidence ribbons about every 2-3 minutes jogging time. Several ribbons in a row with double orange ribbons indicate you are appraoching a turn. Pay close attention at all times and do not assume the runner in front of you knows the course or is following it correctly; he or she could take you off course if you mindlessly follow and don't watch for markers yourself, so stay alert. Remember too, that if you have a pacer and the pacer is leading you, make sure they know how the course is marked and don't assume they will keep you on course.....you both need to pay attention!
Several key intersections are also marked with chalk arrows and/or signs. Night time sections will have reflective markers attached to limbs and trail posts. Please review the map and course to familiarize yourself with bi-directional sections of the course (mainly on the PCT and in and out of Todd's Cabin aid station).
There are five major road crossings (Sunrise Hwy and Hwy 79) on this course. Use extreme caution when crossing the roads and yield to all traffic!
