Event Overview
Scheduled for June 27-28, 2026, the Western States 100-Mile Endurance Run (WSER) stands as the crown jewel of the ultramarathon world. Starting in Olympic Valley, California, and finishing at Placer High School in Auburn, this race is a journey through the rugged Western States Trail. With a history dating back to 1974, it is the oldest 100-mile trail race in the world. The atmosphere is electric, characterized by a mix of high-alpine scenery, grueling desert heat, and a community spirit that is unparalleled in endurance sports. Securing a bib is a feat in itself, but crossing the finish line before the 30-hour cutoff is the ultimate test of human endurance.
Course Details & Terrain
The WSER course is a point-to-point beast that features over 18,000 feet of climbing and a bone-jarring 23,000 feet of descent. The race begins with an immediate 2,500-foot climb to Emigrant Pass. From there, runners navigate high-country snow patches (depending on the year) before entering the infamous 'Canyons.' This middle section is where many races are lost; the steep descents into the canyons of the Deadwood, El Dorado, and Volcano creeks are followed by punishing climbs in stagnant, triple-digit heat. The final 30 miles include the iconic Rucky Chucky river crossing, where runners must navigate a cable across the American River, followed by a series of rolling trails leading to the legendary finish on the track in Auburn.
Who Should Enter? (Beginners vs. Experienced)
Beginners: It is rare for a true 'beginner' to enter WSER due to the strict qualifying race requirements and the lottery system. However, for those new to the 100-mile distance who have managed to secure a spot, the challenge is immense. The primary focus must be on survival and finishing within the 30-hour limit rather than racing for a specific time.
Experienced: For elite ultrarunners and veterans, Western States is the ultimate 'fast' 100-miler. Despite the elevation, the course is remarkably runnable for those with the leg strength to handle the eccentric loading of the descents. Experienced runners will look to break the sub-24-hour mark to earn the coveted silver belt buckle, requiring a sophisticated strategy for heat management and nutrition.
Coach Raye's Race-Day Pro Tips
- Master the 'Active Cooling' Strategy: The heat in the canyons is often the biggest variable. Do not wait until you feel hot to start cooling. Use ice bandanas, douse your hat at every aid station, and keep your core temperature down from mile 30 onwards. Once you redline from heat, it is nearly impossible to recover.
- Save Your Quads for the Last 20: The descent from the start to the river is relentless. It is tempting to fly down the smooth sections, but if you blow your quadriceps in the first 50 miles, you will be reduced to a crawl on the final, runnable 20 miles into Auburn. Practice high-volume downhill training in the months leading up to the race.
- Fuel for the Canyons: The intense heat often shuts down the digestive system. Focus on liquid calories or easily digestible gels during the hottest parts of the day. Avoid heavy solids when your heart rate is elevated during the steep canyon climbs.
