Ten days out from the 2026 Western States 100, the build-up to ultrarunning's most storied race has reached fever pitch, with organisers and competitors alike describing the deepest fields the event has assembled in its half-century history. The 100.2-mile course from Olympic Valley to Auburn, California, climbs roughly 18,000 feet and descends more than 22,000 feet on its net-downhill route through the Sierra Nevada, and on 27 June a field capped at 370 runners will set off into the high country before dawn in pursuit of the silver buckle.
The men's race has been reshaped by the withdrawals of four-time champion and course-record holder Jim Walmsley and of Hayden Hawks, which prompted Hoka to move its sponsor entry to Cocodona 250 champion Dan Green. That leaves Kilian Jornet, third last season, as the projected favourite as he chases an improbable victory fifteen years after his 2011 triumph, with 2022 champion Adam Peterman among the most credentialled challengers in a front pack that runs many names deep. The absence of Walmsley removes a known quantity from the lead group and throws the race tactically open.
The women's field may be deeper still. Defending champion Abby Hall returns to headline a group that includes nine of last year's top ten, among them two-time runner-up Fu-Zhao Xiang, while the newcomers have generated as much buzz as the veterans. Molly Seidel, the 2020 Olympic marathon bronze medallist, makes her hundred-mile debut at the sport's biggest race, and Jennifer Lichter arrives as the Black Canyon 100k course-record holder and one of the form athletes of the spring. The blend of proven mountain runners and high-pedigree road and trail converts gives the women's race an unusually wide range of plausible winners.
As ever, the result will hinge as much on conditions as on credentials. A heavy Sierra snowpack can slow the early high-country miles, the American River crossing at Rucky Chucky introduces a genuine variable late in the day, and the canyons between Foresthill and the river routinely deliver the kind of heat that unravels even the best-laid pacing plans. Crews and pacers will be drilling aid-station logistics over the coming days, while the race's live tracking and broadcast continue to turn a wilderness event into a spectacle followed around the world.
Beyond the buckles, Western States sits at the culmination of the Golden Ticket season and remains the spiritual centre of American 100-mile racing, its prestige undimmed by the rise of the UTMB World Series and the global trail circuit. For Jornet, a win would burnish an already singular legacy; for Hall, a successful defence would cement her among the modern greats; and for debutants such as Seidel, simply finishing the journey to Auburn would mark an arrival on ultrarunning's grandest stage. Ten days remain, and the anticipation in the foothills is building by the hour.
