Event Overview
The Western States 100-Mile Endurance Run (WSER) is the crown jewel of ultra-running. Scheduled for late June 2026, the race begins in Olympic Valley, California, and finishes on the Placer High School track in Auburn. Born from a 1974 experiment by Tevis Cup horse riders, this event has become a pilgrimage for elite athletes and dedicated amateurs alike. The vibe is a mix of high-stakes competition and deep community spirit, characterized by the legendary 'Silver Buckle' awarded to sub-24-hour finishers.
Course Details & Terrain
The course is a point-to-point journey through the Sierra Nevada Mountains. It is notoriously difficult, featuring over 18,000 feet of climbing and nearly 23,000 feet of descent.
The Three Phases of WSER
- The High Country: The first 30 miles are high-altitude and often involve snow crossings. Steep climbs and technical rocky paths dominate.
- The Canyons: Between miles 30 and 70, athletes descend into deep canyons where temperatures frequently exceed 100°F (38°C). This section is famous for its punishing heat and relentless vertical shifts.
- The River & The Finish: Crossing the American River at mile 78 is a milestone, followed by the rolling, runnable trails leading into Auburn.
Who Should Enter? (Beginners vs. Experienced)
Beginners: WSER is not an entry-level race. Entry is lottery-based and requires a qualifying finish at another 100k or 100-mile event. First-timers at Western States must be prepared for extreme temperature fluctuations and significant downhill quad-pounding.
Experienced: For the veteran, WSER is about the sub-24-hour quest. It is one of the fastest 'mountain' hundreds, making pacing critical. If you can handle the heat and the descent, it is a prime venue for an ultra-marathon personal best on a historic stage.
Coach Raye's Race-Day Pro Tips
- Master the Downhill: Most runners blow their quads in the first 30 miles of descent. Practice 'eccentric' strength training to ensure your legs can still run when you hit the flat miles at the end.
- Aggressive Cooling: Use ice bandanas and soak your shirt at every aid station in the canyons. Do not wait until you feel hot; once your core temperature spikes, it is nearly impossible to bring it back down while moving.
- The 30/70 Nutrition Rule: Front-load your calories when it's cool in the morning. When the heat hits in the afternoon, shift toward liquid nutrition and electrolytes as your stomach's ability to digest solids will diminish.
