WSER Course Map and Information

The Western States 100-Mile Endurance Run (WSER) is the world’s foremost 100 mile footrace. The interactive app below gives relevant information for each aid station along the course.

Included on the information tab is a silver buckle pace for a runner’s arrival to each aid station. This represents the arrival clock time needed for a participant to be considered on pace to receive a silver buckle. The silver buckle is given to participants who finish the course in under 24 hours. Often this is achieved by less than 25% of race starters.

Note 1: The data used to build this app (including the GPX of the course itself) was taken from the official Western States 100 Mile Endurance Run website (https://www.wser.org/).

Note 2: The GPX track does not exactly match the course layout. Due to noise in the data collection process there are some discrepancies in the elevation profile as well as the distances between aid stations. However, this is the GPX track published on the WSER website which closely follows the actual course.

Note 3: The app was built with R. The mapping tool uses data from Stamen Maps and makes use of the ggmap package (http://journal.r-project.org/archive/2013-1/kahle-wickham.pdf).

Note 4: This app is best viewed on a desktop computer. Mobile users may have a difficult time using the app.
