It starts with a shotgun blast. 5:00 AM. Olympic Valley. Most people are still tucked into expensive hotel sheets, but 369 runners are currently staring at the silhouette of the Sierras, wondering why they paid money to suffer. The Western States 100 Mile Endurance Run isn't just a race; it’s a weird, beautiful, heat-soaked pilgrimage that has basically defined modern ultrarunning since Gordy Ainsleigh decided his horse was optional in 1974.
He finished in 23 hours and 42 minutes. That one act changed everything.
If you’ve ever looked at a trail map of the Western States Trail, you’ll notice it’s not a loop. It’s a point-to-point journey from the high country of Palisades Tahoe down to the Placer High School track in Auburn. You're traversing land that the Washoe and Nisenan people knew long before gold miners arrived to tear up the dirt. It’s rugged. It’s punishing. Honestly, it’s kind of a miracle that people finish it at all given the 18,000 feet of climbing and 23,000 feet of descent. Your quads don't just get tired—they essentially disintegrate by mile 80.
The Brutal Reality of the Canyons
Most people focus on the high country. The "Escarpment" at mile four is iconic, offering views that make you feel like you're on top of the world. But the high country is a lie. It lures you in with cool morning air and snowy patches. The real race starts when you drop into the canyons.
Between Robinson Flat and Foresthill, the temperature doesn't just rise; it attacks. We're talking about the "Deadwood" and "Eldorado" canyons. It can be 105 degrees in those trenches, with zero airflow and heat radiating off the canyon walls like a convection oven. You’ll see elite athletes—people who train 120 miles a week—sitting in a creek at the bottom of a canyon, staring blankly at a rock because their core temp has redlined.
Sponging is an art form here. At aid stations like Devil’s Thumb, volunteers aren't just handing out electrolytes; they are literally shoving ice down runners' shirts and hats. If you don't manage your temperature in the canyons, your race ends at Michigan Bluff. Period. You’ll see DNF (Did Not Finish) stickers on car bumpers for a reason.
Why the Silver Buckle is the Only Trophy That Matters
In most sports, you want the gold. In Western States, everyone is chasing silver.
There’s a specific rule: finish under 24 hours, and you get the Sterling Silver Belt Buckle. Finish between 24 and 30 hours, and you get the bronze version. It sounds like a small distinction, but it’s the difference between a lifetime achievement and a "glad I finished" moment. The 24-hour mark is the "Golden Hour," though that term is also used for the final hour of the race (29 to 30 hours) when the true drama happens.

The "Golden Hour" at the end of the race—between 10:00 AM and 11:00 AM on Sunday—is arguably more emotional than the winner’s finish. You have people who have been moving for over a day. They are hobbling. They are weeping. Their crews are screaming. Seeing someone cross the line at 29:59:58 is enough to make a grown man cry. It's raw.
The Lottery Problem
You can’t just sign up. You have to qualify by running another 100-miler (or specific 100k races) within a certain time frame. Then, you enter a lottery.
The odds are terrible. Thousands of names go into the hat for a few hundred spots. Some people wait eight, nine, or ten years to get in. Because the race takes place in the Granite Chief Wilderness, the US Forest Service caps the number of starters at 369. That’s it. That’s the magic number. It creates this intense pressure; when you finally get your name pulled, you feel like you have to finish because you might not get another chance for a decade.
The Evolution of the Lead Pack
The Western States 100 Mile Endurance Run has seen a massive shift in how it's raced. Back in the day, it was about survival. Now, it’s a sprint.
Look at Jim Walmsley’s 2019 course record of 14:09:28. Or Courtney Dauwalter’s mind-bending 15:29:33 in 2023. These aren't just "hikes." They are averaging paces that would humble most road runners at a local 10k. The level of professionalism has skyrocketed. We now see "pro" ultrarunners with full support teams, specialized nutrition plans, and carbon-plated trail shoes.
But even with the best gear, the trail is the great equalizer. You can have a $200,000 sponsorship and still get taken out by a bad stomach or a rolled ankle on the California Street section. The trail doesn't care about your Instagram followers.
Rucky Chucky and the River Crossing
Mile 78. This is the spot. The Rucky Chucky crossing of the American River.

In low-water years, you wade across using a cable for balance. In high-water years—when the Sierra snowpack is massive—they have to ferry runners across in rafts. It’s a surreal moment. You’ve been running for 15+ hours, it’s dark, you’re soaking wet, and you’re being boated across a rushing river by volunteers in headlamps.
It’s also where many runners pick up their second pacer. Having a fresh set of legs and a clear brain to guide you through the "Cal Street" section (miles 80-90) is crucial. This part of the course is notoriously "runnable," which is a cruel joke because, at mile 85, nobody feels like running. It’s a mental battleground.
Beyond the Elites: The Spirit of the Trail
While the front-runners get the glory, the back-of-the-packers are the soul of the event. They are the ones navigating the dark with failing headlamps. They are the ones dealing with "the leans"—when your core muscles give out and you literally can't stand up straight.
The aid stations are legendary. Places like Foresthill or Peachstone aren't just stops; they are parties. Volunteers will do anything for you. They’ll pop your blisters. They’ll feed you pierogies. They’ll lie to your face and tell you that you look "great" when you actually look like a walking corpse. That community support is why Western States remains the pinnacle of the sport despite the growth of bigger races like UTMB in France.
Critical Gear and Strategy Mistakes
If you're actually planning to run this or help someone crew, don't ignore the logistics. It’s a nightmare.
- Pacing isn't just for runners: Your crew needs a pacer for their own logistics. Driving between aid stations like Robinson Flat and Dusty Corners involves narrow, winding dirt roads. If your crew is sleep-deprived, they are a danger to themselves.
- The "Salt" Myth: You don't just need salt; you need a balance. Over-salting leads to edema (swelling). You’ll see runners with "sausage fingers" because they popped too many S-Caps.
- Foot Care: The dust on the Western States Trail is like talcum powder. It gets into everything. If you don't use gaiters or change your socks, that dust acts like sandpaper between your toes.
- Lights: The sun goes down fast in the canyons. If you're stuck between aid stations without a high-lumen headlamp, your pace will drop to a crawl.
Why We Keep Coming Back
Why do people obsess over a belt buckle? Honestly, it’s probably because Western States is one of the few places left where you can't fake it. You can't buy your way to the finish line. You can't "hack" 100 miles of heat and vertical gain.
It’s a 100-mile mirror. You see exactly who you are at mile 90 when the sun is coming up and you’re still two miles from the No Hands Bridge. There’s a purity in that suffering that's hard to find in modern life.

How to Prepare for the Western States Journey
If you’re serious about getting involved with the Western States 100 Mile Endurance Run, whether as a runner, volunteer, or spectator, here is how you actually move forward.
1. Secure Your Qualifier
Don't just pick any race. Ensure the race is on the official Western States Qualifying list for the current year. Most people choose races like the Javelina Jundred or Rocky Raccoon. You must finish within the specified time (usually under 30 hours for a 100-miler) to earn your lottery ticket.
2. Volunteer First
The best way to understand the "WS100" vibe is to work an aid station. It gives you a "ticket" in a different sense—it connects you to the community. Contact the Western States Endurance Run Foundation to get on the volunteer list early, as spots fill up months in advance.
3. Study the Heat
If you do get in, your training must include heat acclimatization. This isn't optional. Successful runners use sauna protocols (sitting in 160°F for 20-30 mins post-run) starting three weeks before the race. You have to teach your body to sweat sooner and retain more plasma volume.
4. Plan the Logistics Now
Lodging in Auburn and Olympic Valley disappears the moment the lottery results are announced in December. If you're even thinking about entering the lottery, book refundable accommodation a year in advance.
5. Follow the Science
Research the latest findings on "gut training." To finish Western States, you need to be able to process 60-90 grams of carbohydrates per hour while your body is under extreme heat stress. Practice your fueling in the middle of your hottest long runs.
The Western States Trail is a historic monument. Whether you're running for a sub-24 silver buckle or just trying to make the 30-hour cutoff, the trail demands respect. Respect the heat, respect the canyons, and most importantly, respect the volunteers who make the whole thing possible.
