The course is marked so you can follow it. Orange and black arrows will guide you. Always use common sense and some navigation skills of your own. The basic rule of thumb is do not turn unless instructed to do so. Keep your eyes up and be looking for signage. If you are confused, follow the tracks of those in front of you. Familiarize yourself with the course and have a good sense of where you’re going before race day. Print off the course description and take it with you. Wait for someone who knows the route. Take responsibility for yourself and do not let yourself go awry!
There will be a time cut-off checkpoint at the summit of Boreas Pass. All racers must get over Boreas Pass by 4:15pm to complete loop 3. Racers not reaching this checkpoint by 4:00 pm will be turned around, thus not completing the race. There will be a broom wagon returning from Como – Aid #7 – at 6:00 pm. If you haven’t reached Boreas Pass on your return leg by the time broom wagon reaches you, you will be picked up and your race will be thankfully over.
All racers must complete their conquest before Saturday evening at 7:15 pm.
