Annual ultramarathon in California

The Western States Endurance Run, known commonly as the Western States 100 or Western States, is a 100.2 mile (161 km) ultramarathon that takes place on California's Sierra Nevada Mountains trails each year on the last full weekend of June. Western States is the oldest and one of the most competitive ultramarathons in the United States, and is administered by the nonprofit Western States Endurance Run Foundation. The Western States 100 is one of the five 100 mile races that comprise the Grand Slam of Ultrarunning, which also includes the Old Dominion 100 in Virginia, the Vermont 100 Mile Endurance Run, the Wasatch Front 100 Mile Endurance Run in Utah, and the Leadville Trail 100 in Colorado. One of the more prestigious ultramarathons in the world, it is a qualifier for the UTMB World Series, although the UTMB organization has a major competing race in the same area with a similar course, called "Canyons Endurance Runs by UTMB".

The course was first attempted on foot by twenty soldiers from Fort Riley, Kansas during the 1972 Tevis Cup horse ride event. Because the Tevis Cup imposed a 24 hour time limit, the soldiers started one day before the horses. Seven completed the 100.2 miles, and it was subsequently reported as the first "Auburn Endurance March". In 1974, Gordy Ainsleigh became the first to complete the course in under 24 hours, arriving in Auburn in twenty three hours and forty two minutes. In 1976, Ken “Cowman” Shirk became the second to complete the distance, though 30 minutes over the 24 hour mark. Sixteen runners signed up for the first official Western States Endurance Run in 1977, held in conjunction with the Tevis Cup. Runners were provided with water but were otherwise required to bring their own supplies. Thirteen of the 16 dropped out or were pulled by the 50 mile mark. Of the three remaining runners, only Andy Gonzales finished in the 24 hour time limit set for the horses. The other two, Peter Mattei and Ralph Paffenbarger, finished in 28 hours and 36 minutes (unofficially). Their finishing times led to the establishment of the first sub 30 hour awards. Later that year, the Western States Trail Foundation established the race's first Board of Directors. The following year, 1978, the Western States Endurance Run was made independent of the Tevis Cup and took place in June, a month earlier than the horse ride. There were 21 aid stations and six medical checks. Sixty three runners competed, 30 runners finished, and Pat Smythe became the first woman finisher, finishing with a time of 29 hours and 34 minutes. By 1980, the number of starting runners had increased to 250 people from 3 countries and 21 states. A lottery system for race entry was implemented in 1981. In 1984, the Granite Chief Wilderness was created under the provisions of the 1964 Wilderness Act, and about four miles (6 km) of the Western States trail was within the new boundaries. The wilderness designation prevented the Forest Service from permitting organized events in the area. In 1988, however, the Endurance Run (and the original Trail Ride) was given Congressional permission to continue, but with the number of runners limited to 369, the size of the 1984 field. In 1985, the Western States Endurance Run course was officially measured to an accuracy of one tenth of a mile, resulting in a designated distance of 100.2 miles. In 2017, a wait list was implemented with replacement runners selected from the list to ensure that the 369 allowable starting spots were completely filled.

In 2008, the race was canceled due to bad air quality and smoke from an unprecedented number of wildfires. In 2020, the race was canceled due to the COVID 19 pandemic.

The Western States Endurance Run has followed the same course since 1986, traversing a section of the Western States Trail, a designated National Recreational Trail that stretches from Salt Lake City, Utah, to Sacramento, California. Much of the course is accessible only by foot, horse, or helicopter. The race starts at the base of the Palisades Tahoe ski resort in the west end of the Olympic Valley in California and traverses the Foresthill Divide and through Foresthill. The course then crosses the American River Canyon, ascends through Cool, and finishes at the Placer High School track in Auburn, California. The terrain is quite rugged, often featuring snow on the passes. Temperatures during the run can range from 20 to more than 110 degrees Fahrenheit.

Runners ascend a cumulative total of 18,090 feet (5500 m) and descend a total of 22,970 feet (7000 m) on mountain trails before reaching the finish. Starting at 6,200 feet on the Olympic Valley floor, runners immediately ascend to Emigrant Pass at 8,750 feet, gaining 2,550 feet in elevation over the first 4.5 miles. The trail then descends to around 7,000 feet at the 10 mile mark. Approximately twenty miles in, runners continue down into Duncan Canyon before making a 1,500 foot ascent back up towards Robinson Flat. Between miles 30 and 45, the trail drops to elevation 3,000 feet, at which point runners make the ascent to "Devil's Thumb". From this landmark, runners descend 2,000 feet to cross El Dorado Creek, up 1,500 feet to Michigan Bluff, and then down into the town of Foresthill. At this point, runners pass through the "Cal 1", "Cal 2", and "Cal 3" descents to arrive at the Rocky Chucky river crossing. Once across the American River, just over 20 miles remain. The next climb is through the town of Cool, gaining around 750 feet before sloping downward again.

At 78 miles, runners must ford the American River near the Rucky Chucky crossing. To cross, runners wade with the assistance of a guide rope stretched from bank to bank. However, in high water years, runners are conveyed across the canyon in river rafts.

Because of the length, the race commences at 5 a. m. and continues through the day and into the night.

There are twenty aid stations, including 10 major medical checkpoints.

All entrants that complete the race in less than 30 hours and within race regulations are recognized as official finishers and receive a finisher's medallion.

The top male finisher and the top female finisher are each awarded with the Western States Cougar Trophy. Provided they finish in under 24 hours, they are also declared the winners of the Wendell Robie Cup, a "perpetual" trophy with the names of all winners engraved.

Runners who complete the Western States Endurance Run in less than 24 hours are awarded a hand made silver belt buckle. Runners who complete the Western States Endurance Run in a time between 24 hours and 30 hours are awarded a hand made bronze belt buckle. Milestone belt buckles are also awarded to individuals with 10, 20, and 25 finishes in under 24 hours (the "10 Day", "20 Day", and "25 Day" belt buckles). 1000 Mile and 2500 Mile belt buckles are awarded to those with 10 and 25 official finishes.

Age group awards are given to the top three men and women in the categories: 39 and under; 40 49; 50 59; 60 69; and 70 and over.

The oldest male and female finishers receive awards.
