The Western States 100, one of the most prestigious ultra-marathons in the world, is gearing up for its 53rd edition in 2026, and significant changes are on the horizon. For the first time in its storied history, participants will be permitted to use trekking poles and traction devices like microspikes. This landmark decision follows a vote by the race board to revise its long-standing prohibition against these tools, a modification that has been in discussion for nearly a decade.

Why the Change?
According to Race Director Craig Thornley, this development represents a major evolution for the race. Over the years, there have been ongoing discussions centered around runner safety and performance, especially with the emergence of new equipment types. As Thornley noted, “Ski poles were essentially the equivalent of today’s trekking poles,” highlighting the progression in gear technology.
The Course: A Test of Endurance
Spanning a challenging 100.2 miles, the Western States 100 kicks off in Olympic Valley, California, and ultimately finishes in Auburn, California. The course boasts an impressive ascent of nearly 18,000 feet through the Sierra Nevada mountains, featuring various terrains and climatic conditions. Runners are subjected to everything from ice and snow in the early stages of the race to the intense heat of canyons later on. This ever-changing landscape adds layers of difficulty, making effective equipment a crucial factor for competitors.
Tradition Meets Modernity
Thornley emphasized that the introduction of trekking poles and traction devices balances the heritage of the event with the evolution of the sport. “Our primary goal is to set a benchmark for individual challenge and event organization,” Thornley explained. By acknowledging advancements in running gear while preserving the event’s historic roots, the race aims to uphold its reputation as a leader in ultra-marathon endurance.
Aligning with Global Trends
The regulatory adjustment aligns the Western States 100 with other major ultra-marathons globally. Competitions like the Ultra-Trail du Mont-Blanc (UTMB), Canada’s Fat Dog 120, and Sinister 7 have all embraced the use of trekking poles and traction devices. Many elite runners leverage these tools for improved stability and balance during strenuous climbs and steep descents. Their growing popularity reflects a broader trend within the ultra-running community, where equipment is continuously innovated for enhanced performance.
Listening to Runners’ Feedback
The decision to allow these tools was also prompted by feedback from participants. Thornley noted, “Frequently asked by runners, particularly during years with heavy snowfall, the time seemed right to evolve our rules.” This responsiveness to the athlete’s needs underscores the race’s commitment to ensuring the safety and performance of its participants.
A Future Full of Potential
With these changes, the Western States 100 is poised to embrace a new era of ultra-running, one characterized by adaptability and progress. As the event approaches in 2026, athletes can prepare not only for the physical demands of the race but also for the added support that equipment like poles and microspikes will provide.
The Western States 100 has long stood as a testament to human endurance and spirit, and with its evolving regulations, it continues to foster a community dedicated to pushing the boundaries of what is possible in the ultramarathon realm. As the race evolves, it remains committed to blending tradition with innovation, ensuring that it retains its position as one of the premier ultra-distance races worldwide.
Conclusion
In conclusion, the 2026 edition of the Western States 100 will not only test the mettle of ultra-runners but also provide them with essential tools to enhance their safety and effectiveness on a course renowned for its extremes. As the race adapts to the needs of its athletes while honoring its rich history, the road ahead looks promising for both seasoned participants and newcomers alike.
