Field pace: the median finisher's pace on the segment into this checkpoint, relative to their own whole-race average — right/orange = slower than race pace, left/blue = faster. Green Gate includes the Rucky Chucky river crossing, so its segment time contains the queue and the crossing itself. Arrival times assume the 5:00 local start. Buffer and Tight are computed on 2025 finishers against the 2025 cutoff chart. Runners who missed a cutoff or dropped are not in the data (finishers only).

Green Gate, mile 80

The slowest stretch of the entire course for the median finisher 1.56× their whole-race pace, 20h 29m into the race.

Michigan Bluff, mile 56

The second-hardest segment 1.46× their whole-race pace, 13h 33m into the race.

47.6%
Duncan Canyon — the tightest cutoff

The share of 2025 finishers who cleared Duncan Canyon (mile 24) with under an hour of buffer — the sharpest squeeze on the course.

One more number worth sitting with: the median finisher reaches Foresthill (mile 62) at 8:14 PM and doesn't stop moving until 7:48 AM +1d. Everything after that happens in the dark. If your training plan has no night running in it, the data says it should.

Methodology & sources

Split data: official per-runner checkpoint times for 7 Western States Endurance Run editions (2018–2025), 2,034 finishers at 21 timed checkpoints. Cutoff chart: 2025 official aid station chart (www.wser.org/aid-stations/). All split-derived figures describe finishers only — runners who dropped or missed a cutoff do not appear in split data, so buffer statistics understate how tight cutoffs are for the full field. Medians are used throughout; no figure on this page is modeled or extrapolated.
