Background

The Western States 100 is the oldest 100-mile trail race in North America, starting in Olympic Valley, California, and ending in Auburn, California. The 2025 race is scheduled to begin at 5 a.m. on Saturday, June 28.

Considerations

The field is as usual highly competitive, though this year both Katie Schide and Courtney Dauwalter are notably absent. Weather conditions, including high temperatures and potential wildfires, can significantly impact race outcomes.
