There will be a time cut-off checkpoint at the summit of Boreas Pass. All racers must get over Boreas Pass by 4:30 pm to complete loop 3. Racers not reaching this checkpoint by 4:30 pm will be turned around, thus not completing the race.  There will be a broom wagon returning from 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 given a ride back to the park.

All racers must complete their conquest before Saturday evening at 7:15 pm.
