This is a guide based on leaving an aid station at its cut off and reaching the next at its cut off. Average pace for this 33 hour 100.8 mile race is 19 min 39 sec (19:39) per mile. Individual aid station cut off times have been adjusted for altitude gains, losses, night and last runners who finished previous races.

* There is no Cutoff at Newcomb and Josephine Peak to prevent runners from dropping out there because they could not meet the Cutoff Time. We did this to prevent runners from dropping there because it is extremely difficult to haul them out.
