The Ups and Downs of the Angeles Crest 100 Mile Run

Pacific Crest Trail on Mt. Baden-Powell

Updated June 29, 2018. Elevation profile updated to 2017 AC100.

Switchback after mind-numbing switchback you work up the mountain. White firs and sugar pines give way to lodgepole pines and then the forest begins to thin. Views of the high desert stretch out to Edwards Dry Lake and the Southern Sierra looms hazily in the distance.

This mountain, Baden-Powell, is the second of several big climbs on the Angeles Crest 100 Mile course. While it reaches the highest elevation on the course — about 9250′ — it is not the longest climb or the ascent with the most elevation gain. Which climb on the course is the most difficult is an all together different question, and one that can only be answered on race day.

This elevation profile of the 2017 AC100 course (PDF) was created in SportTracks from a runner’s GPX track. The profile uses elevations corrected with pkan’s Elevation Correction Plugin and NED 1/3 arc second DEMs and a conservative elevation data smoothing setting.

The mileage is from the GPX track and is the calculated distance over the terrain, including any extra wanderings of the runner at aid stations and on the course. Placemark locations, mileages, and elevation gains and losses are approximate.

Using the smoothed, corrected elevations, the cumulative elevation gain on the AC100 course worked out to around 18,520′ and the loss to around 23,215′. These are conservative values. The gain and loss could easily be a bit more.
