Western States Endurance Run by UTMB: Route, live tracking & how to watch

The Western States 100, or Western States Endurance Run, is an iconic ultramarathon that takes place in California, USA, covering 100.2 miles through the Sierra Nevada mountain range. 

Now also part of the UTMB World Series, the race is held annually on the last weekend of June and is one of the oldest and most challenging 100-mile events in the world. 

The Western States 100 has a rich history that dates back to 1974, when it was first held as the Western States Trail Ride. It was inspired by the 19th-century Pony Express, and the course follows the historic Western States Trail. 

Over the years, it has attracted some of the world’s best ultrarunners and finishing the race is considered a major accomplishment in the ultra-running community. 

Here is our full guide to learning about the event, following it live or even taking part.

Western States 100 Route

The races starts in Olympic Valley, California and passes through remote and rugged territory in the Sierra Nevada mountain range to the finish at Placer High School in the small town of Auburn.

The trail features more than 18,000ft of ascent and descends nearly 23,000ft as runners climb from the valley floor and travel west, following original trails used by gold and silver miners in the 1800s. 

There are 20 checkpoints between the start and the finish, all of which have cut-offs and ten of which have major medical assistance. The tenth checkpoint comes in just over half-way into the race at Michigan Bluff and has a cut-off time of 9:55pm. 

The Devil’s Thumb section one of the most challenging as runners take on a steep ascent from the river valley to the top of a ridge, while Michigan Bluff features another steep climb and stunning views.  

The route has been largely unchanged since 1986 and will only be altered due to weather conditions – which can be volatile. 

At around 78 miles, runners must cross the American River. This can be dangerous and during the race a guide rope is stretched across the river, with rafts used in high-water years. 


Western States UTMB Running Stones

In 2022, the Western States 100 agreed to become part of the UTMB World Series, meaning it offers Running Stones to participants which allow entry for the lottery for the UTMB World Finals at the legendary Ultra-Trail du Mont Blanc

As a 100M race, the Western States 100 offers four Running Stones to those who complete it. 

Facts, Tips & FAQ 

The race’s origins date back to 1955 when Wendell Robie and five horsemen rode the Western States Trail from the post office in Tahoe City to Auburn to prove that horses could cover 100 miles in one day. 

Those who finish the race in under 24 hours receive the prestigious silver belt buckle, with a bronze equivalent on offer for a sub-30-hour effort. 

Support crews are only permitted at specific aid stations and must stay within 200 yards of those areas. 

Runners can be accompanied by one pacer at a time, starting from the Foresthill aid station to the finish. Those leaving Michigan Bluff after 8pm can use a pacer.

Who is taking part at Western States 2024?  

Americans Jim Walmsley and Katie Schide, both UTMB winners, look to be the big favourites this year.

Last year Walmsley memorably ended his quest to finally add a UTMB title in Chamonix to his CV and as well as being the current course record holder at Western States, he’s also a three-time winner.

And on the women’s side the 2022 UTMB winner Katie Schide will be looking to go one better than last year’s second place here behind Dauwalter.

She underlined her form with victory at the Canyons Endurance Runs by UTMB at the end of April.
