**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 100.1 mile race is 19 min., 47 sec. (19:47) per mile. Individual aid station cut off times have been adjusted for altitude gains, losses, night and last runners who finished previous races. ** Westfork is not an aid station. You will pass thru Westfork 3 times. This is For Reference Only.
*In 2019(orginal course) there was a pacer access at Chilao(mi 44.8) and Chantry Flats(mi 75.4).
In 2023 we’re bypassing Chantry. In 2023 there is pacer access at Chilao(mi 44.4) and Redbox(mi 59.5). Pacers will have to run that last 40 miles.
