Western States 100 2026: Bouillard shatters the record

What happened in the Sierra Canyons

The Western States 100 covers over 100 miles from Olympic Valley to Auburn, winding through the High Country of the Sierra Nevada, descending into the notorious canyons, and crossing the American River. The race has been the gold standard in ultratrail since 1974. And rarely has a record felt so overdue: Walmsley’s 14:09:28 from 2019 was seen as nearly untouchable.

Bouillard didn’t just shave it-he shattered it. His 13:46:15 means sub-14 hours, a mark long considered a theoretical ceiling. What’s even more striking is the depth at the front: with Francesco Puppi making his 100-mile debut in 13:51:08 and Ryan Montgomery in 13:53:55, three runners dipped under the old record. Such a podium has never been seen in Auburn.

From DNF to record in twelve months

The real story isn’t a split-it’s an arc. Reading only the time misses what carried this victory.

What the record means for your own running

A sub-14-hour 100-mile race is a different world from your everyday training. Yet embedded in that race day is a lesson that applies to every distance: the weather dictates the pacing, not your ego. Bouillard and Puppi could only maintain that record pace because the conditions allowed it. In a heatwave year, the same plan would have been a sure-fire recipe for a DNF.

For you, that means your target time is a hypothesis, not a contract. Trying to hold the same splits at 32 °C as you would at 14 °C will leave you just as blown up in the canyons as it does on your local summer loop. We dissected how heat and fueling decide the outcome over a long day in our hydration-vest test. And if you want to grasp the mechanics of big mountain races, the lessons from the Zugspitz Ultratrail offer the European take on the same physics.

The second lesson is about the comeback. A DNF isn’t a verdict; it’s an intermediate time. Bouillard needed twelve months to turn an exit at mile 80 into a course record. That’s the real headline of race day, no matter how far you run yourself.

Cool-down

Click on a question to reveal the answer.

How significant is a 23-minute lead over 100 miles?

Enormous. Over 100 miles, that’s roughly 14 seconds per mile Bouillard was faster than the previous record. On this terrain, over this distance, and across nearly 14 hours, such a jump is extraordinary. Course records here usually fall by minutes, not quarters of a second.

Why is cool weather so crucial?

The canyons in the middle of the course heat up dramatically in the sun, often exceeding 40 °C. Heat forces slower pacing, more breaks at aid stations, and greater fluid loss. When it stays cool, that braking factor disappears. Nearly every fast Western States time has come in cooler years.

What about the women’s race?

A record fell there too. Jenn Lichter, 30, from Missoula, won her first-ever 100-mile race in 15:28:05, shattering Courtney Dauwalter’s course record. Riley Brady finished second in 15:42:14. A debut victory with a record is a genuine rarity in ultratrail.

Can I sign up for Western States as a hobby runner?

Only via qualification and then a lottery. First you need an accepted qualifier, then you enter a draw that can take several years. The path to Auburn is itself a long-term project, even for strong ultrarunners-not a last-minute entry.
