Ranking Years by Difficulty

Median finish times 1986 and onward. It should be noted that both 1995 and 1998 the finish time cutoff was extended to 32 hours. While those years were arguably very difficult they do skew the median times.

YearMedian TimeRank
199528:15:001<--- Hardest
201224:48:2936<--- Easiest

Diamond Groups

Here is an interesting way to help you determine what splits you might want to target.  This idea came from The Great Ed Willson of Eugene, OR and coded by Julie Schulte. The splits for each segment are separated into finish hour groups. Let’s say you want to run 22-23 hours. You can look at the splits that the 22-23 hour finishers ran. Outliers to the positive ran slower for that segment that other 22-23 hour finishers, while outliers to the negative ran faster than the group. The perfect split for your time goal may be right in the middle of your diamond group.

Runner Surveys

Beginning in 2014, there has been an independent survey conducted by ultralive.net as runners go through check-in the day before the race in Squaw Valley. Participation is completely voluntary.

Tevis and Western States Finishers

The Western States Endurance Run honors its beginnings from the Western States Trail Ride (Tevis Cup). Through the years, inspired by the draw of the Western States Trail, these athletes have met the challenge of both events.
