The short answer

The Western States Endurance Run is a 100.2-mile point-to-point trail race from Olympic Valley, near Lake Tahoe, to Auburn, California. It starts at 5:00 a.m. on the last full weekend in June and finishers have 30 hours. Runners under 24 hours earn a silver buckle.

The course climbs about 18,000 feet and drops nearly 23,000 feet, from snow on the high passes to hot, deep canyons and a ford of the American River at mile 78. A Forest Service permit limits the field to 369 runners.

Most places are drawn in a December lottery that rewards persistence: your tickets double every year you apply without getting in. In 2026, 11,328 people applied.

How to get a place

You need two things before you can enter the lottery. You must be at least 18 on race day, and you must finish a race from the official qualifying list, inside its listed time, during the one-year window. For 2027 that window runs from 3 November 2025 to 8 November 2026. Virtual events do not count, and a race that is not on the list cannot be used.

If your name is drawn on 5 December, you get an UltraSignup invitation and have ten days to pay the $575 entry fee plus the online fee. Miss that and you lose the place and every ticket you had built up.

Seventy-five more names are drawn for an ordered wait list. When an entrant withdraws, the next person on the list gets the place. The exception is a place that belongs to a sponsor, an aid station or a raffle winner, where that sponsor can name a replacement who also applied to the lottery.

Why your tickets double

Every lottery you enter without getting in raises your chances next time. In your nth lottery you hold 2 to the power of n minus 1 tickets: one ticket the first time, two the second, then four, eight, sixteen and so on. Since the 2020 lottery the years no longer have to be consecutive, but you must requalify and reapply each time.

If you are drawn for the wait list and decline, or you withdraw before 1 p.m. on the Friday before the race, you keep your ticket count.

The other ways in

A minority of the 369 places are not drawn at all. The race calls them automatic entries. They still need a valid qualifier.

  • The top ten women and top ten men from the previous year.
  • Up to 30 places for HOKA Golden Ticket winners, from six qualifying races.
  • One runner chosen by each club that sponsors and staffs an aid station. This is usually a volunteer with at least three years at that station.
  • Runners named under certain sponsor agreements, and members of the board.
  • The two pioneers, Gordy Ainsleigh and Cowman A-Moo-Ha.
  • Nine-time finishers going for a tenth, and 18 and 19-time finishers going for their 19th and 20th.
  • Winners of the twice-yearly raffle, drawn 18 and 12 months before the race.
  • The Greg Soderlund Silver Legend entry, one place for a runner aged 60 or over.

Golden Ticket races for 2027

At three of the six races the top two women and men qualify, and at the other three the top three. If someone ahead of you declines, the place rolls down to the next finisher.

What are your lottery odds?

The hat keeps getting fuller. Applicants rose from 1,786 in 2011 to 11,328 in 2026, and the ticket count from 2,286 to 93,003. A first-time applicant in 2026 held one of those 93,003 tickets.

Use the calculator to see roughly where you stand. It starts from the latest published hat and lets you change the number of draws. The 2027 hat appears online after registration closes on 21 November, and it will almost certainly be bigger.

The race used 260 draws for its own 2025 odds simulation. The real number changes each year with the count of automatic entries.

An estimate for planning, not an official Western States figure. Each draw removes the selected runner's tickets from the hat, so later tickets are worth slightly more. The race publishes the real hat online after registration closes.

What it costs

The entry fee for 2027 is $575 plus the online booking fee. That is the only cost the race sets. Travel, lodging, crew and a qualifying race are yours to budget, and they often add up to more than the entry.

Book a room as soon as you are in. The race says most motels near the start are full by January or February. There is also no official transport from the finish in Auburn back to Olympic Valley, so plan how your car, or your crew, gets from one end of the course to the other.

Things to budget for

  • A qualifying race inside the window, with its own entry and travel.
  • Two or three nights near the start for registration on Friday, plus somewhere to sleep in Auburn after the finish.
  • Flights or a long drive, and a crew vehicle that can handle narrow mountain roads.
  • Optional Memorial Day weekend training runs on the last 70 miles. They sold out in 2026.
  • Kit you may not own yet, such as two reliable lights, heat gear and shoes for long descents.

The course, section by section

Western States follows the middle of the historic Western States Trail, used by gold and silver miners in the 1850s. It has followed the same basic route since 1986, unless snow forces a change. Much of it can only be reached on foot, by horse or by helicopter.

The high country: start to Robinson Flat (miles 0 to 30)

You start at about 6,200 feet in Olympic Valley, site of the 1960 Winter Olympics, and climb 2,550 feet to Emigrant Pass at 8,750 feet in the first 4½ miles. That is the highest point of the race. From there the trail crosses the Granite Chief Wilderness, roughly miles 6 to 10, which is why the field is fixed at 369.

In a big snow year this section can be slushy or icy, and the race has used an alternate snow route several times. The first crew access is not until Duncan Canyon at mile 24.4.

The canyons: Robinson Flat to Foresthill (miles 30 to 62)

After the high ridges the trail drops into deep canyons, with steep descents to the creeks and long climbs back out through Last Chance, Devil's Thumb and El Dorado Creek. This is where heat usually bites. The race warns that pace in the canyons can vary a lot with temperature and humidity.

Michigan Bluff at 55.7 miles and Foresthill at 62 are the big crew stops. Foresthill is where most runners pick up a pacer, and where the race tells everyone to carry a light, whatever the time.

Cal Street and the river: Foresthill to Rucky Chucky (miles 62 to 78)

The California Street section runs mostly downhill above the American River, through three aid stations that crews cannot reach. Many runners arrive here in the evening and finish it in the dark.

At mile 78 you ford the American River near Rucky Chucky, holding a guide rope with a team of 125 people on hand. In high-water years runners cross by raft instead. Do not try the crossing on a training run.

The last 22 miles: Green Gate to Auburn (miles 78 to 100.2)

From the river the trail climbs to Green Gate, then rolls through Auburn Lake Trails, Quarry Road and Pointed Rocks towards town. Reflectors mark the last 38 miles for the night.

At Robie Point you leave the trail for the streets of Auburn, and crews and friends can run in with you. You finish on the Placer High School track.

Aid stations and cutoffs

Every cutoff is a deadline for leaving the aid station, not for arriving. Leave after it and you are out of the race. A few remote stations have default cutoffs, marked with an asterisk, which simply match the next station's cutoff. They exist for emergencies.

The race is blunt that cutoffs are not a pacing guide. They are generous early on, and if you are close to them you are in trouble. The race expects a 30-hour runner at Foresthill around 10:45 p.m., an hour inside the cutoff. Use the 30-hour column as your real target.

Heat, snow and the river

The race tells runners to prepare for anything from 20°F to above 110°F. In Auburn the average high on the last weekend of June is about 89°F, with a low around 59°F. The canyons can be far hotter: in 1989 the heat radiating off the rocks was measured at 114°F.

Heat shapes the finish rate more than anything else. In 2006 the high in Auburn reached 101°F and only 52.6% finished, the lowest rate since 1986. In 2026 the high was 73°F, the coolest since 2012, and 87.0% finished.

Snow is the other variable. The high country can be clear or buried, and in big years the race has rerouted the start and used boats at the river. Check the snowpack updates in spring before you decide on shoes and traction.

Rules that shape your plan

Pacers

  • One pacer at a time, from Foresthill at mile 62 to the finish.
  • If you leave Michigan Bluff after 8 p.m., you can have a pacer from there.
  • Pacers can change at Foresthill, the near side of Rucky Chucky, Green Gate, Pointed Rocks and Robie Point.
  • Since 2025 nobody can pace or crew you on Bath Road. Pacers wait inside the Foresthill aid station.
  • Pacers must be 18 or over and carry only their own supplies. Carrying anything for the runner, known as muling, is banned.

Drop bags

  • One bag per aid station, at the stations marked in the table.
  • It must fit through a 6 by 8 inch opening and be no longer than 16 inches. No paper bags or boxes.
  • Drop them off on Friday between 9 a.m. and 1 p.m. in Olympic Valley, and collect them at the finish by 3 p.m. on Sunday.
  • Pacers cannot have their own bags, so their supplies go in yours. Put warm clothes and a spare light in the night-time bags.

On the trail

  • Poles are allowed anywhere, and you can drop or collect them where crews or drop bags are allowed. There are no shoe restrictions, so microspikes are fine.
  • The race recommends carrying two LED lights, because almost half the course may be covered in the dark.
  • There are no weigh-ins. Medical staff judge how you look, feel and think.
  • To drop out, hand your wristband to an aid station captain. Without it you count as lost.
  • No dogs, smoking or litter anywhere on the course.

How many people finish?

Of the 370 starters in 2026, 322 finished. That 87.0% is the highest finish rate in the race's history for a full field, just ahead of 2023 (86.5%) and 2019 (86.4%). Over the last ten races it has ranged from 66.0% to 87.0%.

The two gaps in the chart are 2008, cancelled because of wildfires, and 2020, cancelled because of COVID-19.

Records and buckles

Both course records fell in 2026. Vincent Bouillard of France ran 13:46:15 and Jennifer Lichter ran 15:28:05 in her first 100-mile race. The race counts records from 1985, when the course became 100.2 miles.

Finishers under 30 hours earn a bronze belt buckle and those under 24 hours a silver one. Ann Trason holds the record for wins, with 14, and Scott Jurek won seven in a row from 1999 to 2005.

One of the most famous finishes came in 2015, when Gunhild Swanson set the women's 70 and over record of 29:59:54, six seconds inside the 30-hour limit.

The 2026 race

The 53rd race, on 27 and 28 June 2026, was unusually cool, and it showed. Vincent Bouillard passed Francesco Puppi late in the race to win in 13:46:15, and the first three men all finished under 14 hours. Jennifer Lichter broke the women's record by running 15:28:05 in her first 100-mile race.

Further back, 136 runners earned silver buckles under 24 hours, the most since 2012.

From horses to a lottery

The trail came first. In 1955 Wendell Robie and five other riders rode from Tahoe City to Auburn to show that horses could cover 100 miles in a day. That ride became the Tevis Cup.

On 3 August 1974 Gordy Ainsleigh lined up with the horses on foot and reached Auburn in 23 hours and 42 minutes. Ken "Cowman" Shirk did the same in 1976. In 1977 fourteen men started the first official run. Andy Gonzales won in 22:57, and when Peter Mattei and Ralph Paffenbarger arrived together in 28:36, the race created the 30-hour finish.

Training for Western States

Think of it as a descending race with a hot middle. You lose nearly 23,000 feet, much of it after the canyons have already worn your legs down. Long downhill running, heat preparation and comfortable night running matter as much as the total miles.

Our 100-mile plan gives you the structure. For Western States, build in regular steep descents, some sessions in heat or extra layers in the weeks before the race, and at least a few long runs that go into the dark. If you live at low altitude, remember that the first 30 miles are mostly above 6,000 feet.

The race holds three training runs over Memorial Day weekend on the last 70 miles of the course, with aid and buses. You do not need an entry to join. In 2026 entrants could register for about two weeks after the lottery, before it opened to everyone, and all three days sold out.

Getting there and race week

The start is in Olympic Valley at Palisades Tahoe, near the north shore of Lake Tahoe. Truckee is about 20 minutes away and Tahoe City about 15. The finish is in Auburn, in the Sierra foothills, so you will be staying at both ends.

Registration on Friday, between 9 a.m. and 1 p.m. near the start arch, is compulsory. So is the race meeting that afternoon (2 p.m. in 2026). On race morning, food and coffee are served at the Olympic Plaza from 3:30 a.m. After the finish there is a free breakfast for entrants at Placer High School from 8 a.m. to noon on Sunday, and the awards ceremony is on Sunday too.

Crewing and watching

Crews can only meet runners at the stations listed below. Away from Foresthill, crews are limited to one vehicle per runner, and motorhomes can only go to Foresthill. Several stops are reached by shuttle or on foot, so pack light and allow plenty of time.

Watching from home

The race has broadcast live since 2021, using Starlink since 2022 to reach remote parts of the trail. Live coverage and tracking are linked from the official website on race weekend.

If you are there in person, the 2026 race-week agenda included a pre-dawn hike to Emigrant Pass to watch runners come over the first climb.

Running for good at Western States

The race depends on more than 1,500 volunteers, about four for every runner. The river crossing alone has 125. Aid station clubs that volunteer for years can nominate one runner, so long service is one of the routes in.

The Western States Endurance Run Foundation is a nonprofit that maintains the trail with the Tevis Cup organisers, the Forest Service and state parks. Its volunteer steward programme scheduled 14 open trail-work days in 2025. You can join those without a race entry.

The race has also been a research lab for more than 40 years. In 1981 Dr Walter Bortz carried a refrigerated centrifuge up to Michigan Bluff to study endorphins, one of the earliest studies linking them to exercise. At the finish, the race sends its waste through a facility that sorts recycling and compost, and offers leftover food to volunteers first.

If you are not in this year

Most applicants do not get in, so it helps to plan more than one year ahead. Keep qualifying and keep applying, because your tickets keep doubling.

In the meantime, a Golden Ticket race such as Black Canyon 100K, the Canyons 100K or CCC is a great race in its own right. And a Western States finish earns UTMB Running Stones (four in 2025) towards the UTMB lottery in Chamonix.
