Western States 100 2026: Elite Field Breakdown 12 Days Out
In 12 days, at 5am from the Squaw Valley start in California, the world's best ultrarunners will set off on 100 miles and 18,000 feet of elevation to Auburn. The Western States 100-Mile Endurance Run is North America's most iconic ultra. In 2026, the elite field ranks among the deepest of the decade.
Race Context
The men's course record remains Jim Walmsley's 2019 performance: 14:46:44. Still an exceptional benchmark. No serious sub-14:46 attempt is expected this year — Sierra snowpack will make the opening miles more demanding than usual.
The 2025-2026 Sierra Nevada snowpack is significantly above average. River crossings — particularly in the final third — are expected to be technically demanding and potentially dangerous. This favors runners with course-specific experience and works against record attempts.
Men's Field
Tyler Green (US) arrives on form from his 2025 TNF50 victory. He hasn't finished Western States before — that's an open variable. How he handles the hot canyon miles (60-80) will be decisive.
Vincent Bouillard (France) finished 3rd in 2024 and returns with solid course knowledge. Known for his consistency in difficult conditions — the high-snow course may suit him well.
Eli Hemming (US) has run this course multiple times and remains one of its specialists. On a technically demanding course in challenging conditions, course-specific heat preparation is a significant advantage.
Women's Field
Courtney Dauwalter (US) is going for her 4th Western States title. She's already won 3 times. The women's course record is 16:32:32 (Ellie Greenwood, 2012). Dauwalter isn't in record mode this year — she's in race domination mode, with an effort management strategy built for the long game. Her recent form was on full display at the Chianti Ultra Trail 120K, where she crushed the course record by over an hour.
Megan Roche (US) makes her first WS100 start. A physician and elite runner, Roche has an exceptional physiological understanding of her effort. How she handles the unknown-course variable is the open question.
Sabrina Stanley (Canada) has deep familiarity with the course and California conditions. She's a solid podium contender.
Weather and Course Variables
WSER organization has confirmed the American River crossing will be at high water. Runners need to navigate ford crossings carefully. Hypothermia risk exists in the early high-altitude sections.
Canyon heat remains the usual differentiating variable: miles 60-78 cross exposed sections where temperatures can exceed 100°F even in late afternoon. Crew access is allowed at aid stations.
